Overview — what is Gorlin syndrome?

A starting point for the whole document: definition, prevalence, the nature of the syndrome, and why surveillance is needed. Suitable for every audience as an initial read.

Definition and synonyms

Gorlin syndrome, also known as NBCCS (Nevoid Basal Cell Carcinoma Syndrome) or basal cell nevus syndrome (BCC), is a hereditary genetic disorder that causes an increased tendency to develop various tumors — mainly basal cell carcinoma (BCC) skin cancers — alongside characteristic skeletal, odontogenic (mouth and jaw), neurological, and cardiological features.

ICD-10 code: Q87.89 · OMIM: 109400 (PTCH1) · 620343 (SUFU).

The story in brief

  • Genetics: autosomal dominant inheritance. A 50% risk of passing it on to each child. The main gene is PTCH1 (chromosome 9q22); less common is SUFU (10q24).
  • Prevalence: estimated at about 1:31,000 to 1:164,000 worldwide.
  • Penetrance: nearly complete (90%+) — almost everyone who carries the mutation will develop at least one of the manifestations. But the expression varies dramatically between people, even within the same family.
  • The main manifestations: multiple BCC skin tumors (sometimes hundreds over a lifetime), odontogenic keratocysts in the jaws, palmoplantar pits, calcification of the falx cerebri (a membrane in the brain), and skeletal features (bifid ribs, macrocephaly).
  • Risk of additional tumors: medulloblastoma (a childhood brain tumor) — low risk with PTCH1 (~2%), significantly higher with SUFU (~20–30%). Cardiac and ovarian fibroma.
  • Life expectancy: nearly normal. With proper surveillance most manifestations can be controlled. The biggest danger is increased exposure to radiation — which is what generates additional BCCs.

Important disclaimer

This document is informational material, not medical advice. Every treatment decision must be made together with the treating physician. The information is current as of July 2026 and will become outdated — check the last-updated date in the footer.

The statistics and protocols are drawn from up-to-date professional sources (GeneReviews, NCCN, JCO, BJD, studies published 2023–2025). Where the evidence is partial or conflicting, this is stated explicitly.

Just diagnosed? Take a breath.

This tab is for you if you (or your child/family member) were recently diagnosed. The pace here is calm — we go over what it means, what you need to do in the coming months, and what you don't need to do.

The most important thing to know first

Gorlin syndrome is a chronic condition you live with — not an illness you treat and are done with.

Most people with the syndrome live full lives, with a life expectancy close to normal. Four principles will determine how smooth the road is:

01

Regular surveillance

The real danger isn't the tumor that appears — it's the tumor that grows quietly. Follow-up every 3–6 months with a dermatologist makes it possible to catch a BCC when it's 2 mm instead of 2 cm. The difference: a 10-minute procedure versus a 3-hour Mohs surgery with a visible scar.

02

Sun protection

UV radiation is the number-1 trigger for new BCC tumors. Every hour of exposure without protection is an accumulating debt you'll pay 10–15 years later. SPF 50, a wide-brimmed hat, long sleeves in summer — not a leisure activity but a daily discipline to adopt.

03

Less medical radiation

X-rays, CT and repeated scans are ionizing radiation. A Gorlin patient's body is more sensitive to it than average, and every cumulative exposure raises the risk of secondary tumors. The rule: before any test, ask "Can we do an MRI or ultrasound instead?".

04

Community and emotional support

A diagnosis of a genetic condition is shaking. People walking the same path — in Gorlin syndrome patient associations and in Facebook groups worldwide — ease the burden in a way no physician can. This support helps you stay sane even when everything is under medical control.

What to do in the first weeks — a roadmap

A Gorlin diagnosis opens six doors, each of which you need to walk through in the first three months. Not all in the same week — but all of them need to be scheduled. Most people at this point don't yet realize they're facing several medical stops, different specialties, and a few bureaucratic steps. This is the practical roadmap:

  1. 1

    Book a visit with a dermatologist familiar with the syndrome

    Why it matters: this is the fixed team that will accompany you for life. A dermatologist who knows what Gorlin looks like — and not just a sporadic BCC — will identify tumors early, decide correctly when to cut and when to watch, and know when to switch to systemic therapy.

    How: a referral from your primary-care physician to a dermatology clinic at a major medical center. State "Gorlin syndrome" up front so they schedule you with a doctor who is familiar with it. Wait times vary by health system; flagging a "suspected skin tumour" often shortens them.

  2. 2

    Genetic counseling + molecular testing

    Why it matters: there are two possible genes — PTCH1 (~85% of cases) and SUFU (~5–10%). This isn't a technicality: with SUFU the risk of medulloblastoma (a childhood brain tumor) is 10–20 times higher, and accordingly the surveillance protocol in children is a brain MRI every 4 months until age 3. Without knowing which gene you have, surveillance can't be planned correctly.

    How: a referral to a genetic counselor at a genetics institute (every academic hospital has one). The first session is ~45 minutes, covering inheritance and family. A blood sample is sent to the lab — results in 4–10 weeks. Important: the test may be covered by your health plan or insurer if diagnostic criteria are met — worth verifying beforehand.

  3. 3

    Panoramic radiograph of the jaw

    Why it matters: 65–75% of Gorlin patients develop odontogenic keratocysts (OKCs) in the jaw. They aren't dangerous — but if they grow undetected, they can damage the jawbone and teeth. In children they are treated differently than in adults (marsupialization instead of surgery), so time of detection changes how they're managed.

    How: a referral to an oral & maxillofacial surgeon at a hospital or dental school. The radiograph itself takes 5 minutes, with reading at the same visit. Recommended frequency going forward: every 12–18 months.

  4. 4

    Baseline echocardiogram

    Why it matters: about 2–5% of patients have a cardiac fibroma — a benign tumor that is usually asymptomatic, but rarely causes arrhythmia or hemodynamic obstruction. A single baseline scan rules out the risk; if normal, gentle follow-up every 2–3 years.

    How: a referral to a cardiologist through your health provider. A transthoracic echocardiogram — 30 minutes, no radiation, non-invasive. Results usually the same day.

  5. 5

    If there are children under age 5 + a SUFU mutation: brain MRI

    Why it matters: medulloblastoma is the major risk in Gorlin-SUFU in childhood, and the median age of onset is 16.5 months. Early detection dramatically changes the prognosis — from catching it at an early stage, to prompt treatment and sparing radiation to the head (which in Gorlin patients is dangerous in its own right).

    How: a referral to pediatric neuro-oncology at a specialist children's center. The MRI is done under brief sedation (because young children don't stay still for 30 minutes). Recommended frequency: every 4 months from birth to age 3, then every 6 months to age 5.

  6. 6

    Connect with a Gorlin syndrome patient association

    Why it matters: this isn't a nicety — it's infrastructure. Patient associations connect patients, know which doctors are familiar with the syndrome in practice (and not just on paper), and help you navigate your health provider and any disability or social-security services when the bureaucracy begins. It's also psychological: one conversation with someone who has walked the same path saves months of searching alone.

    How: reach out to a Gorlin syndrome association — for example the Gorlin Syndrome Alliance (US), the Gorlin Syndrome Group (UK), or a national/local group where you live (see Sources & Links). Most reply within days, free of charge and with no obligation.

A huge tip before the first visit

Save the link to this page (gorlin.help) or print the "Clinical Info for Physicians" tab. At the first visit with a new doctor there are at least 8 terms you hear for the first time — PTCH1, SUFU, OKC, panoramic, fibroma, BCC, Mohs, HHI. There's no way to remember it all during the conversation. It's better to have a document to return to afterward, and an hour to read quietly at home. You can also send the link to the doctor the day before the visit — some doctors appreciate that.

Frequently asked questions (FAQ)

Is it hereditary? Could I pass it on to my children?

Yes. Gorlin syndrome is autosomal dominant — every child born to an affected person has a 50% chance of inheriting the mutation. If the parent is not affected, the chance is close to zero (unless there is a de novo case, a new mutation — which accounts for about 20–30% of cases).

Family-planning options include preimplantation genetic diagnosis (PGD/IVF), prenatal diagnosis (CVS or amniocentesis), or a regular pregnancy with genetic counseling.

What are my chances of getting skin cancer?

High — but not as dangerous as it sounds. BCC tumors are local skin cancers that almost never metastasize. The real danger is the extent of the treatments and the local damage to the skin. With follow-up every 3–6 months with a dermatologist, tumors are caught small and easy to remove.

Average age at the first BCC: 20–30. By age 40 — about 80% of patients have at least one.

Do I have to stop going out in the sun?

Not stop, but protect. Ultraviolet radiation is the main trigger. A practical strategy:

  • Broad-spectrum SPF 50+ sunscreen, every morning, even on a cloudy day.
  • Protective (UPF) clothing, a wide-brimmed hat, sunglasses.
  • Avoid direct exposure between 10:00 and 16:00.
  • Outdoor activity — in the shade, or in the early/late hours.

The beach, sports, life — none of it is canceled. Just with awareness.

Am I not allowed to have an X-ray or CT?

Not "not allowed," but you should reduce it to the medical minimum. A Gorlin patient's body is sensitive to ionizing radiation and may develop BCC tumors where it was exposed. Rules of thumb:

  • When possible — prefer MRI or ultrasound over CT.
  • Routine dental radiographs — every 12–18 months (no more), with lead shielding.
  • Chest X-ray / CT — only if there is a clear medical reason.
  • Tell every doctor/technician: "I have Gorlin syndrome, please prefer a non-radiation alternative if possible."
Where is this treated?

Care is multidisciplinary and is usually best coordinated through major academic medical centers, which bring the relevant specialties together:

  • Dermatology — for BCC surveillance and treatment.
  • Oral & maxillofacial surgery — for odontogenic keratocysts (often based at a hospital or dental school).
  • Clinical genetics — for testing and counseling.
  • Pediatric oncology / neuro-oncology — where medulloblastoma is a concern.

A Gorlin syndrome patient association can help you find doctors and centers familiar with the syndrome near you.

Does my child need to know? How do I explain it?

Yes — in an age-appropriate way. A child who knows what is happening to their body is less anxious, not more. See the "For Kids (11+)" tab in this document — it was written especially for them. For under age 11, adapt the explanation to their level (simple sentences: "I have something special in my body, so I go to the doctor more than others").

Principle: don't hide, don't frighten. Normalize the follow-up as part of life.

I've been depressed/anxious since the diagnosis. Is that normal?

Completely normal. A diagnosis of a chronic genetic condition is a well-known emotional trigger. Studies show a high rate of anxiety and depression among Gorlin patients, especially around times of a new tumor being found or surgery. If the feeling interferes with daily functioning, see a psychologist or psychiatrist. CBT and acceptance-based therapies (ACT) have been shown to be effective. Support groups, too — through the Gorlin association or on Facebook (UK group: Gorlin Syndrome Group) — help a great deal.

Is there a "cure"? A remedy?

No, and not in the near term. But the treatment of the manifestations has improved significantly: Hedgehog pathway inhibitors (Vismodegib, Sonidegib) can greatly reduce the number of new BCCs. Active trials (2025–2026) of topical Patidegib, Itraconazole and other new drugs are adding options. The research is moving — see the "Research & Trials" tab.

Who your medical team is

Gorlin syndrome requires a multidisciplinary team. These are the people you should be in touch with:

SpecialistWhyFrequency
Dermatologist (skin doctor)Full skin exams, BCC removal, managing systemic therapyEvery 3–6 months
Geneticist / genetic counselorConfirming the mutation, counseling for relatives and regarding pregnancyInitial visit + as needed
Oral & maxillofacial surgeonMonitoring odontogenic keratocysts, surgeryPanoramic radiograph every 12–24 months
CardiologistEchocardiogram to detect cardiac fibromaBaseline + every 2–3 years if normal
Gynecologist (for women)Pelvic ultrasound for ovarian fibromasEvery 2–3 years
Neurologist / neuro-oncologistMainly if SUFU or suspected medulloblastomaDepends on the mutation and age
PsychologistCoping, anxiety, body imageAs needed

Privacy and employment — things to consider

A diagnosis of a genetic condition may raise practical questions:

  • Private life/health insurance: disability-rights protections vary by country, and insurers may require a health questionnaire. It's worth understanding your local rights and consulting an insurance expert before signing.
  • Sun-exposed occupations: professions requiring prolonged sun exposure (agriculture, construction, lifeguarding) call for extra thought. Not an absolute barrier — but active protection at all times.
  • Disability & social-security support: depends on the severity of the clinical manifestation. If there is significant functional impairment, you may be eligible for disability benefits through your country's social-security or disability services. A patient association can help guide you.

Gorlin 101 — for the physician encountering it for the first time

Who is this section for? For a physician of any specialty meeting a Gorlin patient for the first time, or who knows the syndrome from their own specialty's angle and wants to understand the full spectrum. A quick overview — 5 minutes of reading.

The syndrome in brief

Gorlin syndrome (NBCCS) is an autosomal dominant disorder caused by a mutation in PTCH1 (85%) or SUFU (5–10%). Prevalence 1:31,000–1:164,000. Nearly complete penetrance — but the clinical expression varies dramatically, even within the same family. A patient may present with a key manifestation in your field before the genetic diagnosis is even known.

What each specialist needs to know — by field

Dermatology
What you'll see: multiple BCCs at a young age

Gorlin patients develop dozens to hundreds of BCCs over a lifetime. First BCC at age 20–30 (rarely before 10). Skin surveillance every 3–6 months. Removal by surgery, Mohs, PDT, or topical therapy. Radiation to treat a BCC is contraindicated — it makes it worse.

What to know outside your field: patients also have OKCs in the jaw (annual panoramic), cardiac fibroma (baseline echo), and if SUFU — a childhood medulloblastoma risk.

Oral & maxillofacial surgery
What you'll see: multiple / recurrent OKCs

65–75% of patients. Recurrence 30–40% with enucleation alone — consider peripheral ostectomy and/or Carnoy's solution. In children — primary marsupialization. Minimize imaging: panoramic every 12–18 months, no more.

What to know outside your field: these patients are sensitive to ionizing radiation; minimize jaw CT. They also need close skin surveillance (BCCs), and a cardiac evaluation.

Cardiology
What you'll see: cardiac fibroma

Prevalence 2–5%. Sometimes detected prenatally. Most — asymptomatic. Surgery only for hemodynamic obstruction, arrhythmia, or rapid growth. Baseline echo, follow-up every 2–3 years.

What to know outside your field: the patient in front of you likely has skin BCCs and jaw OKCs. If you find a fibroma in an infant — refer to genetics to rule out/confirm Gorlin.

Neurology / neuro-oncology
What you'll see: childhood medulloblastoma

Risk 1.7% in PTCH1, 20–30% in SUFU. Subtype: SHH-activated, Desmoplastic/Nodular. Median age 16.5 months in SUFU. Protocol: brain MRI every 4 months until age 3, every 6 months until age 5 in SUFU. Avoid radiation where possible — chemo-only protocols under discussion.

What to know outside your field: the patient will need skin surveillance (BCCs) and jaw imaging (OKCs) for life.

Genetics
What you'll see: referral for counseling after clinical diagnosis

PTCH1 vs SUFU stratification is critical: it determines the intensity of brain surveillance and the medulloblastoma risk. 20–30% de novo. 15–20% with no mutation in known genes — consider NGS/WES. Counseling for relatives and for family planning (PGD, CVS).

What to know outside your field: diverse clinical expression — refer to a dermatologist, oral & maxillofacial surgeon, cardiologist. The patient needs a multidisciplinary team.

Gynecology
What you'll see: ovarian fibromas

15–25% of women with Gorlin, 75% bilateral. Most — asymptomatic, ultrasound every 2–3 years. Conservative approach: avoid oophorectomy unless necessary.

What to know outside your field: Gorlin patients of reproductive age need genetic counseling (PGD/IVF). There is also parallel skin and jaw surveillance.

Ophthalmology
What you'll see: congenital eye anomalies

Strabismus (63%), hypertelorism (45%), congenital cataract (18%), coloboma (9%). Early referral for infants/children.

What to know outside your field: eye anomalies are a minor diagnostic criterion. If the child in front of you also has frontal bossing and a large head — consider a genetics referral.

Radiology
What to know: these patients are radiation-sensitive

Ionizing radiation (CT, X-ray) increases secondary BCCs. Principle: MRI/US first, CT only if there is no medical alternative. Dental panoramic no more than every 12–18 months. Mammography — consider alternative breast MRI in high-risk cases. Document cumulative radiation exposure.

What to know outside your field: notify the ordering team. Ensure maximal lead shielding if CT is required.

Psychology / psychiatry
What you'll see: chronic emotional burden

A high rate of anxiety and depression, especially around repeated surgeries, the discovery of new tumors, and impaired body image. CBT and ACT are effective. Risk factors: isolation, lack of community, the first BCC discovery. Younger patients need normalization.

What to know outside your field: this is a chronic genetic condition with repeated surgeries. The burden accumulates. Referral to support groups (the Gorlin association) is part of the treatment.

A guiding principle for every specialist: a Gorlin patient requires a multidisciplinary team. Even if they come to you with a focused problem — the manifestations cross systems. Make sure they also have a dermatologist, an oral & maxillofacial surgeon, and a geneticist. If not — refer.

Genetics and molecular biology

Genes

  • PTCH1 (9q22.3) — ~50–85% of cases. A tumor suppressor in the Hedgehog/Patched-Smoothened pathway.
  • SUFU (10q24.32) — a few percent, but critical clinical significance: a 10–20 times higher medulloblastoma risk.
  • PTCH2 — reported in rare cases; clinical significance not yet established.
  • ~15–20% of cases with no mutation identified in PTCH1/SUFU on standard testing; consider NGS/WES.

Inheritance

  • Autosomal dominant, ~90% penetrance by age 30.
  • Variable expression even within the same family.
  • ~20–30% de novo.
Clinically critical — stratification by gene:
  • PTCH1: medulloblastoma risk ~1.7%.
  • SUFU: risk ~20–30%, median age of onset 16.5 months, Desmoplastic/Nodular SHH-activated subtype. Requires a brain MRI every 4 months from birth to age 3, and then every 6 months to age 5.

Options for preconception/prenatal diagnosis

  • PGD (preimplantation genetic diagnosis) — requires prior identification of the familial mutation.
  • CVS / amniocentesis — in an established pregnancy.
  • Genetic counseling before pregnancy is recommended for all patients of reproductive age.

Diagnostic criteria (Kimonis 1997, updated Bree 2011)

Diagnosis: 2 major criteria or 1 major + 2 minor.

Major criteria

  1. ≥2 BCCs, or one BCC < age 30, or ≥10 BCC nevi.
  2. Odontogenic Keratocyst (OKC) — histologically confirmed.
  3. ≥3 palmoplantar pits (palmar/plantar pits).
  4. Ectopic intracranial calcification (typically: falx cerebri, lamellar pattern) — before age 20.
  5. A family history of Gorlin syndrome.

Minor criteria

  1. Rib/vertebral anomalies (bifid ribs, hemivertebra, fusion).
  2. Relative macrocephaly.
  3. Cleft lip/palate.
  4. Cardiac or ovarian fibroma.
  5. Medulloblastoma (especially < age 5).
  6. Lymphomesenteric cysts.

  • Screening of at-risk relatives.
  • Very early BCC or medulloblastoma before age 5.

Clinical manifestations — detail by system

Dermatology

First BCC at age 20–30 (rare <10). By age 40 — 80% of patients. Average count 10–40+ over a lifetime, some with 100+. Sites: face (>90%), neck, trunk. Types: Nodular (80%), Superficial (15%), Infiltrative/Morpheaform, Basosquamous (5%, aggressive).

Oral & maxillofacial — OKCs

65–75% of patients. 50% of cases multiple/bilateral. Age at diagnosis: 10–30. Recurrence rate: enucleation alone 30–40%; +peripheral ostectomy 10–20%; marsupialization → enucleation 0–15%; +Carnoy's solution ~5%. Recommended: a combined approach in children.

Skeleton

60–75% with at least one anomaly: Bifid ribs (60%), vertebral anomalies (50%), Frontal bossing (50–70%), Macrocephaly (30–40%), cleft lip/palate (5%), polydactyly (5–10%).

Palmoplantar pits

≥85% by age 20–40. 2–3mm diameter, 1–3mm depth. Variable symmetry. ≥3 — a major criterion, specificity >95%.

Neurology

Falx cerebri calcification in 90% by age 30, lamellar pattern on CT. Mild cognitive impairment in 5–10%. Medulloblastoma — see above.

Cardiology

Cardiac fibroma 2–5%. Sometimes detected prenatally. Most — asymptomatic. Indications for surgery: hemodynamic obstruction, arrhythmia, growth.

Ophthalmology

Congenital anomalies in 8–45%: strabismus 63%, congenital cataract 18%, coloboma 9%, hypertelorism 45%. Early referral.

Gynecology

Ovarian fibromas in 15–25% of women, 75% bilateral. Usually asymptomatic. Conservative — avoid oophorectomy if possible.

Surveillance protocols — 2024–2025 consensus

SystemFrequencyImaging/exam
SkinPediatric annually, adolescents every 6–12 mo, adults every 3–6 moFull skin exam, dermoscopy, baseline photography
Teeth/mouthPediatric every 12–18 mo, adults every 2–3 years if normalPanoramic, clinical exam
Brain (SUFU)Every 4 mo age 0–3, every 6 mo age 3–5High-res brain MRI, without sedation if possible
Brain (PTCH1)Clinical only; imaging as symptoms dictate
HeartBaseline in infancy, then every 2–3 years if normalEcho, cardiac MRI for characterization
Pelvis (women)Every 2–3 yearsPelvic ultrasound
EyesEarly pediatric if a congenital anomalyOphthalmologic exam
Radiation avoidance — critical: Gorlin patients are hypersensitive to ionizing radiation. Prefer MRI/US over CT, limit routine panoramics (no more often than every 12–18 mo), avoid routine mammography — consider breast MRI in high-risk cases.

BCC treatment — up-to-date options

Local therapy

  • Surgical excision with 4–5 mm margins — the standard.
  • Mohs surgery — preferred on the face, at high-risk sites, or for morpheaform/infiltrative lesions.
  • PDT (Photodynamic Therapy) — for superficial lesions. ALA/MAL + blue light.
  • Topical 5-FU / Imiquimod 5% — for superficial lesions, efficacy 50–80%.
  • Cryotherapy — for thin superficial lesions.
  • Radiation — contraindicated! Increases secondary BCC.

Systemic therapy — Hedgehog inhibitors (HHI)

Vismodegib (Erivedge)
  • 150 mg PO/day. FDA approved 2012.
  • Response: ORR 50–65%, CR 25–35%.
  • Adverse events: dysgeusia 44–58%, alopecia 49–66%, muscle cramps 54–71%, weight loss 44–56%, fatigue 32–39%.
  • Pregnancy Cat X — absolute contraception required.
Sonidegib (Odomzo)
  • 200 mg PO/day (preferred over 400 mg, better tolerability).
  • 2024 retrospective data: Sonidegib 200 superior to Vismodegib 150 — ORR 61.8% (CR 45.4%, PR 16.3%) [MDPI Cancers 2024].
  • 2026 update: a systematic review (Doyle et al., Head & Neck 2026) and a FAERS pharmacovigilance analysis (Jedlowski et al., AJD 2026) confirm: Vismodegib — a higher incidence of dysgeusia and alopecia; Sonidegib — neutropenia and CPK elevation. The choice depends on the side-effect profile the patient is sensitive to.
Drug Holiday / Intermittent Dosing

An evolving practice 2023–2025: week-on/week-off or month-on/month-off cycles. Maintaining efficacy while reducing side effects. Best individualized.

Treatments in development / active trials
  • Topical Patidegib gel 2% — Phase 2 published in BJD April 2025: 63% CR in treated lesions [BJD 2025]. Phase 3 (Sol-Gel/SGT-610) completed enrollment in August 2025 at 43 sites, ~140 patients; top-line results expected Q4 2026 [Sol-Gel].
  • Itraconazole / SUBA-Itraconazole (off-target HHI) — 57.7% response with ≥30% reduction (Phase IIb HP2001, n=38, 477 lesions). A comparative PK study in Malaysia is underway, final sampling May 2026, bioanalysis ~4 weeks. An NDA via 505(b)(2) is expected later in 2026 [INTI 03/2026].
  • Itraconazole + Arsenic Trioxide — an experimental combination, 75% Hedgehog suppression.
  • Sonidegib + PDT (NCT06623201) — recruiting.
  • SkinJect (D-MNA) — Doxorubicin microneedle array New (July '26) — a dissolving microneedle patch for local intradermal delivery into BCC lesions. A non-surgical, repeatable approach. Medicus Pharma: ODD from the FDA (04/2026), RPDD (06/2026); a registrational Phase 2b planned in Gorlin patients (SKNJCT-004, up to 50 patients, 200µg). An Expanded Access IND pathway in collaboration with the GSA. Investigational.

Treatment of OKC and medulloblastoma

OKC

  1. First line, especially in children: Marsupialization/decompression 8–10 months → enucleation with peripheral ostectomy.
  2. Adjuvant: Carnoy's solution (if available; chloroform has been removed in some countries — modified Carnoy's). Reduces recurrence to ~5%.
  3. Cryotherapy — an alternative to Carnoy's.
  4. Post-op follow-up: annual panoramic for 5 years, then every 2–3.
  5. New in 2025: a case report — piezotome-assisted peripheral ostectomy + PRF (Platelet-Rich Fibrin) showed complete bone remodeling after 36 months. A promising tissue-sparing approach.

Medulloblastoma (SHH-activated, Desmoplastic/MBEN)

  • Principle: spare radiation whenever possible — to prevent secondary BCCs.
  • Chemo-only protocols under study for favorable-risk SHH-MB.
  • SMO inhibitors have a potential role as targeted therapy; multidisciplinary discussion.
  • Prognosis: worse than sporadic SHH-MB, ~60–70% 5-year survival.

Recent clinical updates — 2024–2026 timeline

This section is organized chronologically. Each item is dated and labeled. The most recent findings are shown first. Updated with every version of the document.
  • June 2026 SkinJect (D-MNA) — a non-surgical local approach to BCC enters the regulatory pathwayNew (July '26) Medicus Pharma is advancing SkinJect (D-MNA) — a dissolving microneedle patch with Doxorubicin, delivered intradermally directly into the BCC lesion. The idea: a local, repeatable, non-surgical treatment — a high drug concentration in the lesion with minimal systemic exposure, via a mechanism of direct cytotoxicity + immunogenic cell death. On April 17, 2026, an Orphan Drug Designation (ODD) application was filed with the FDA for BCC in Gorlin, and on June 15, 2026, a Rare Pediatric Disease Designation (RPDD) application was filed. A registrational Phase 2b trial is planned (SKNJCT-004): up to 50 Gorlin patients, 200µg dose, primary endpoint — complete visual clearance in ≥50% of target lesions at week 10, with the option to treat several lesions in parallel. Early Phase 2 data (SKNJCT-003, in sporadic BCC): 73% clinical clearance and 40% histologic CR at day 57 in the 200µg cohort, side effects limited to the application site, no SAEs. In collaboration with the Gorlin Syndrome Alliance (GSA), an Expanded Access IND pathway is being advanced for compassionate access for Gorlin patients with multiple or inoperable BCCs.

  • May 2026 Sonidegib vs Vismodegib — two new comparative publications A systematic review and meta-analysis (Doyle et al., Head & Neck) showed high efficacy of both inhibitors in head-and-neck laBCC/mBCC. A complementary FAERS analysis (Jedlowski et al., AJD) sharpens the side-effect profile: Vismodegib with significantly higher reporting odds for alopecia and taste changes; Sonidegib with neutropenia — a new finding. Both with increased reporting odds for cSCC. The choice depends on the patient's profile and the drug's half-life (Vismodegib 4–12 days, Sonidegib 28–30 days).

Recommended questions the patient can ask

To give the patient before the visit — or to print and bring:

  • Which mutation was I diagnosed with (PTCH1, SUFU, other)? How does that change my surveillance?
  • What is the surveillance frequency you recommend, based on my clinical presentation?
  • Are there new BCCs that justify switching to systemic therapy (HHI)?
  • Am I a candidate for a clinical trial (Patidegib, Itraconazole)?
  • If I'm on an HHI: should we consider a drug holiday?
  • What is the recommended frequency for a panoramic? Echocardiogram? Pelvic ultrasound?
  • Which imaging should be preferred over CT/X-ray?
  • Genetic counseling for family members — how do we start?
  • If I have a child with SUFU — who is the neuro-oncologist who will manage the MRI?
  • Referral to a psychologist/support group — who is recommended?

Knowledge gaps / areas to keep watching

  1. Echocardiogram frequency in asymptomatic adults — no consensus.
  2. Medulloblastoma screening in PTCH1 — NCCN does not recommend it, some centers do perform a baseline.
  3. Itraconazole long-term — missing more than two years of follow-up (NDA expected 2026 — new data may emerge).
  4. Patidegib Phase 3 — preliminary results expected Q4 2026.
  5. Vismodegib vs Sonidegib head-to-head — missing a prospective RCT (2026 reviews sharpen the side-effect profile differences).
  6. Predicting OKC recurrence — no validated scoring system.
  7. Prognosis of SUFU-related medulloblastoma — small cohorts.
  8. RCTs of Gorlin-specific psychotherapy — missing.

Hey. So you have Gorlin syndrome. What does that mean?

This tab is written especially for you — teens aged 11 and up. No complicated words, no Latin, no talking to you like you're a patient. Just the truth, plain and simple.

This tab is written especially for you — teens aged 11 and up. No complicated words, no Latin, no talking to you like you're a patient. Just the truth, plain and simple.

Choose the wording:

What even is "Gorlin syndrome"?

In short

Gorlin syndrome is something you were born with. It's not an illness you caught from someone, and not something you caused. It's written in your genes — in the code that made you — since before you were born.

People who have the syndrome live completely normal lives: school, friends, sports, vacations, work, family. But their body needs a little more attention in certain places — mainly the skin, the mouth, and the jaw.

Why the name "Gorlin"?

Dr. Robert Gorlin was an American doctor who first described the syndrome in 1960. The name just stuck. Sometimes it's also called NBCCS — those are the initials of "Nevoid Basal Cell Carcinoma Syndrome." Complicated? Yes. Usually people just say "Gorlin."

What does it mean about me?

It means three main things:

  1. You'll go to doctors more than your friends do. It's not because you're sick. It's because the doctors check that everything's OK — and if something pops up, they catch it early and it's easy to treat.
  2. The sun is a bit stronger for your skin. That doesn't mean don't go outside. It means protect yourself: sunscreen, a hat, a shirt. Like an athlete who works with their gear before a game.
  3. You're not alone. There are many hundreds of thousands of people with Gorlin around the world. There are patient associations, and Facebook groups where you can talk with others your age.

Questions you might have

Am I going to die from this?

No. People with Gorlin live about as long as everyone else. The biggest risk — skin cancers called BCC — are local: they don't move from their spot in the body. You remove them, and that's it. With good follow-up at a skin doctor, they're treated when they're very small.

Can I play soccer outside?

Sure. You just want to put on sunscreen beforehand, prefer playing when the sun is less harsh (not midday in summer), and use a hat if you can. Sport is amazing for your health — mentally and physically.

Do I have to tell my classmates?

You don't owe anyone anything. It's your story, and you decide who to share it with. Some people tell one good friend so that someone knows. Others keep it to themselves. Both are fine. If a kid teases you about it — that's not OK, and there are people you can rely on: a parent, a counselor, a teacher.

Why do I have to go to so many doctors?

Because what they're doing is surveillance, not treatment. When a doctor checks your skin or a dental X-ray, they want to make sure everything's OK. If something small starts — they catch it before it becomes a big problem. It's like a mechanic checking your car once a year — not because it's broken, but so it doesn't break down.

Will my future kids get this too?

That's an important question, and you'll explore it when you decide you want to know. The chance is 50% for each child. But there are modern ways to choose — there are tests done even before pregnancy. When the time comes, you'll get counseling. Right now — there's no need to worry. You're 11–17, you have plenty of time.

Why am I not allowed to have X-rays?

It's not forbidden — it's just not ideal to do more than you need. X-rays are radiation, and for your skin that's not the best. So when possible, doctors will choose a different test (ultrasound, MRI). When it's really needed — they do it. It's not a drama, just caution.

Why did this happen to me?

Not because of anything you did, that Mom or Dad did, or that the family did. It's just genetics — like one person is born with blue eyes and another with brown. This gene is in the family, or it appeared in you for the first time. There's no reason to look for someone to "blame." It's just part of who you are.

Will I have to take medicine my whole life?

Not necessarily. Most people with Gorlin don't take daily medicine. When you start getting a lot of BCC tumors on the skin, there are special drugs that help slow them down — but that's not always needed. Every patient is their own case.

Can I talk with other kids who have this?

Yes! Gorlin syndrome patient associations connect families and kids, and in the Facebook groups there are teens from around the world. Ask your parent to help you connect — it really helps to know there are other people who understand exactly what you're going through.

5 things worth knowing for life

  1. Your body is not your enemy. It's just a body. Everyone is born with something different. Yours includes Gorlin.
  2. Sun is fun, but sunscreen is a rule. SPF 50, every morning. It becomes routine like brushing your teeth.
  3. Ask the doctor everything. There's no stupid question. A good doctor will explain everything at your level, not your parents'.
  4. You don't have to tell everyone. It's your privacy. Choose who you share it with.
  5. If you feel sad or scared a lot — talk. With a parent, a friend, a counselor, a psychologist. Feelings are part of this — and it's OK to ask for help.

What the doctors really do — at your level

So far we've talked about surveillance, sun, and feelings. But you might already know that some of the follow-up also includes treatments — small procedures, tests, things that sound scary but really don't have to be. The sections here explain what really happens, without hiding anything — but also without scaring you.

Each section is closed, and you open only what interests you.

Skin procedures — removing BCC tumors

BCC tumors are the most common thing in Gorlin syndrome. They're tumors that are not dangerous in most cases — they don't spread to other organs in the body. But they need to be removed because they grow slowly in place.

What actually happens?

A skin doctor (dermatologist) spots a tumor during a routine exam. Sometimes it's a tiny spot you didn't even feel. And then:

  • Local anesthesia — a small injection that numbs just the spot. You don't feel a thing.
  • Excision — the doctor cuts out the tumor and a small margin around it. Takes 10–20 minutes.
  • Stitches — sometimes a few stitches, sometimes just a special bandage.
  • Healing — a week or two, with a bandage. You get back to normal quickly.
And there's also a special surgery called "Mohs"

For tumors on the face or in sensitive places, there's a method called Mohs — the doctor removes one layer, checks it under a microscope, and only if needed — continues. That way as little healthy skin as possible is removed. It takes longer but it's worth it.

And there are also treatments without surgery

For superficial, small tumors, sometimes a special cream (Imiquimod) is applied or a light treatment (PDT) is done — with no cutting at all. The doctor decides what fits best.

How many times will this happen to me?

It varies a lot. Some people with Gorlin remove one tumor every few years. Some need more. There's no way to know in advance — which is why follow-up with the skin doctor is important: when you catch it early, the procedure is small and simple.

Mouth and jaw procedures — cysts

In Gorlin, cysts sometimes form in the jaw — small fluid-filled sacs that grow slowly inside the jawbone. They're not cancerous and not dangerous, but they need to be treated so they don't press on teeth or bone.

How are they found?

Usually on a panoramic dental radiograph — a wide image where you can see the whole jaw. The cyst looks like a roundish dark patch. Sometimes it's found by chance, and sometimes you feel swelling or pressure.

What do they do?
  • Option 1 — "drainage" (marsupialization): the doctor makes a small opening in the cyst so the fluid comes out slowly. The cyst shrinks over months. It's less aggressive, and preferred in children.
  • Option 2 — full removal: after the cyst has shrunk, or if it's small to begin with, the doctor removes it surgically. This is done under anesthesia (local or general, depending on the size).
  • Follow-up after: a panoramic radiograph once a year for a few years, to make sure it doesn't come back.
Does it hurt?

During the procedure — no, because you're numb or asleep. After — there's swelling and discomfort for a few days, treated with regular painkillers. Most kids get back to normal within a week.

And what about teeth?

Sometimes a cyst grows next to a tooth or pushes teeth around. The doctor will try to save the teeth, but sometimes one tooth needs to come out. That's a situation the oral & maxillofacial surgeon plans for in advance.

My body — things you might have noticed

Gorlin syndrome doesn't only affect skin and teeth. It also causes a few features in the body that you may have already noticed. They don't interfere with function in most cases — but it's good for you to know what they are.

A larger head (macrocephaly)

Many people with Gorlin have a head that's a bit larger than average. It doesn't say anything about what's inside — it's just structure. If your head circumference was measured on the larger side — that's part of the syndrome and not a reason to worry.

Prominent forehead (frontal bossing)

In some kids with Gorlin, the forehead is a bit more prominent than usual. This too is a structural feature — cosmetic only, not medical.

Different ribs

On a chest X-ray you can sometimes see a "split" rib (bifid rib) — a rib whose end splits into two. It doesn't hurt, doesn't interfere with breathing, and you can't feel it at all. The doctor might note it, but there's nothing to do — and nothing that needs doing.

Small pits on the palms

This is one of the most characteristic signs: tiny sunken dots on the palms or soles. They're 2–3 mm in size and don't hurt. Not everyone sees them — sometimes you need to look closely. They're harmless and don't need treatment.

Tip: if you wet your palms and look under a strong light, you can see them easily. Some people actually think it's kind of cool — a unique mark that only you have.

Delayed teeth / teeth in an unusual spot

Because of the cysts in the jaw, sometimes permanent teeth are delayed in coming in, or they come in a different spot. The dentist keeps track of this and plans ahead.

Eyes

In a small share of kids there's a slight difference between the eyes (hypertelorism) or a mild squint. If there is — an eye doctor keeps track and treats it. If there isn't — great.

Can I do sports?

Yes! The skeletal features of Gorlin don't limit physical activity. You can run, swim, play soccer, ride a bike — like everyone. Just remember sun protection during outdoor activity.

Medicines — when they're given and what they do

Most kids with Gorlin don't need daily medicine. But when you reach an older age and a lot of BCC tumors start appearing, there are drugs that can help.

Drugs that slow tumors down

They're called "Hedgehog Inhibitors." Hedgehog is the name of a pathway in cells — not the hedgehog from the game. The drugs block this pathway, and tumors shrink or stop growing.

  • Vismodegib and Sonidegib — pills you take every day.
  • They have side effects: a change in taste (food tastes different), hair loss (it comes back when you stop), muscle cramps.
  • Sometimes they're taken in "cycles" — a month on, a month off — to make it easier.
New ointments

There's a new drug in trials called Patidegib — an ointment applied directly to the skin. The advantage: fewer side effects because the drug doesn't go into the whole body. Still being tested, but it's a promising direction.

When is this relevant?

Usually not at your age. Most drug treatment starts at age 20–30+, when a lot of BCCs start appearing. At your age, the main treatment is surveillance + sun protection. But it's good to know what's ahead — so you're not surprised.

Brain scan (MRI) — for those who need it

Not all kids with Gorlin need a brain MRI — but some do, especially if you have a mutation called SUFU (your parents can tell you). If you've already had an MRI — you know what it is.

What is an MRI?

A machine that photographs the inside of the body using a magnet — no radiation (and that's important for us!). You lie inside a tunnel that makes a loud noise, with headphones. It takes 20–40 minutes. It doesn't hurt at all.

Why is it done?

In kids with a SUFU mutation, there's a small chance of a brain tumor called medulloblastoma. The MRI checks that everything's OK. In the vast majority of cases — everything is fine. And even if something is found, it's caught very early and it's much easier to treat.

Until when?

Usually this follow-up is done until age 5, and after that the risk drops a lot. If you're over 5 and no longer getting an MRI — it's a sign that everything's fine.

Yes! The skeletal features of Gorlin don't limit physical activity. You can run, swim, play basketball, ride a bike — like everyone. Just remember sun protection during outdoor activity.

Medicines — when they're given and what they do

Most kids with Gorlin don't need daily medicine. But when you reach an older age and a lot of BCC tumors start appearing, there are drugs that can help.

Drugs that slow tumors down

They're called "Hedgehog Inhibitors." Hedgehog is the name of a pathway in cells — not the hedgehog from the game. The drugs block this pathway, and tumors shrink or stop growing.

  • Vismodegib and Sonidegib — pills you take every day.
  • They have side effects: a change in taste (food tastes different), hair loss (it comes back when you stop), muscle cramps.
  • Sometimes they're taken in "cycles" — a month on, a month off — to make it easier.
New ointments

There's a new drug in trials called Patidegib — an ointment applied directly to the skin. The advantage: fewer side effects because the drug doesn't go into the whole body. Still being tested, but it's a promising direction.

When is this relevant?

Usually not at your age. Most drug treatment starts at age 20–30+, when a lot of BCCs start appearing. At your age, the main treatment is surveillance + sun protection. But it's good to know what's ahead — so you're not surprised.

Brain scan (MRI) — for those who need it

Not all kids with Gorlin need a brain MRI — but some do, especially if you have a mutation called SUFU (your parents can tell you). If you've already had an MRI — you know what it is.

What is an MRI?

A machine that photographs the inside of the body using a magnet — no radiation (and that's important for us!). You lie inside a tunnel that makes a loud noise, with headphones. It takes 20–40 minutes. It doesn't hurt at all.

Why is it done?

In kids with a SUFU mutation, there's a small chance of a brain tumor called medulloblastoma. The MRI checks that everything's OK. In the vast majority of cases — everything is fine. And even if something is found, it's caught very early and it's much easier to treat.

Until when?

Usually this follow-up is done until age 5, and after that the risk drops a lot. If you're over 5 and no longer getting an MRI — it's a sign that everything's fine.

Research, trials and advances — 2024–2026 (updated July 2026)

This section updates the fastest. The goal: to give the patient a tool to follow along, understand what's available, and when it's worth checking whether they're a fit for a clinical trial. Recommended to check every 3–6 months for updates.

Therapeutic advances — what's new 2024–2026

1. Patidegib gel 2% — topical

A Hedgehog inhibitor in an ointment — minimizing systemic absorption, and therefore fewer side effects like dysgeusia and alopecia. Phase 2 results were published in the British Journal of Dermatology in April 2025 (63% complete response in treated lesions). Phase 3 (Sol-Gel/SGT-610) completed enrollment in August 2025 — ~140 patients at 43 sites in the US, Canada and Europe. Top-line results expected Q4 2026.

2. Itraconazole — an old drug, a new use

A long-established, inexpensive antifungal drug found to be an indirect Hedgehog inhibitor. Phase IIb data (HP2001): 38 patients, 477 lesions, 57.7% response with ≥30% reduction. SUBA-Itraconazole (a proprietary amorphous formulation with improved absorption) is in development. In 2024 a PIND was filed with the FDA; in 2026 a Type C meeting was granted. The company (Inhibitor Therapeutics) is choosing a 505(b)(2) pathway — a PK study is underway in Malaysia, final sampling May 2026, followed by an NDA.

3. Sonidegib + PDT — combination

NCT06623201 — a trial combining a Hedgehog inhibitor (Sonidegib) with photodynamic therapy. Active, recruiting. The idea: synergy — less systemic drug, fewer side effects, increased efficacy. ClinicalTrials.gov NCT06623201

4. Itraconazole + Arsenic Trioxide (historical)

A 2016 Stanford study (Ally et al., JAMA Dermatology): a sequential combination reduced GLI1 mRNA by 75% from baseline in mBCC patients resistant to SMO inhibitors. No patient showed tumor shrinkage — possibly due to transient GLI1 suppression with sequential dosing. Research value as a proof-of-concept; not clinical practice. PMID 26765315

5. Drug Holiday Protocols

The MIKIE study (Lancet Oncology 2017) established two intermittent Vismodegib regimens (12 weeks on / 8 weeks off, and 24/8). Later studies (2023–2025) added quicker regimens (week-on/off, month-on/off). Maintaining efficacy with a significant reduction in side effects. Especially recommended in BCNS given the long-term treatment. Lancet Oncology MIKIE · Curr Treat Options Oncol 2025 review

6. SkinJect (D-MNA) — a microneedle patch with Doxorubicin New (July '26)

A new, non-surgical approach: a patch with dissolving microneedles that release Doxorubicin directly into the BCC lesion (intradermal), with a high local concentration and minimal systemic exposure. The advantage for a Gorlin patient — a treatment that can be repeated across multiple lesions, as an alternative to repeated surgeries. Medicus Pharma filed Orphan Drug Designation (April 2026) and Rare Pediatric Disease Designation (June 2026) requests with the FDA, and is planning a registrational Phase 2b trial in Gorlin patients (SKNJCT-004, up to 50 patients, 200µg dose, endpoint — complete clearance in ≥50% of lesions at week 10). In collaboration with the Gorlin Syndrome Alliance (GSA), an Expanded Access IND pathway is being advanced for compassionate access. Still investigational, not yet approved.

How to join a clinical trial

  1. Find a trial that fits — TrialFinder, ClinicalTrials.gov, or through an association.
  2. Review the inclusion/exclusion criteria carefully. Most trials require: a certain age, a minimum number of BCCs, a period without other treatment.
  3. Contact the trial team through the contact details on the site. Most reply within days.
  4. If the trial isn't in your country — check whether travel/lodging is covered (some trials offer it).
  5. Consult your treating physician before deciding. Things to check: fit with your clinical profile, familiarity with the investigating team, the risk versus benefit.
  6. Informed consent — read it carefully. Ask about anything that isn't clear. You are entitled to withdraw from the trial at any stage.
