Show answer and explanation
Correct answer: D. Missing clavicles
- A. Calcification of the falx cerebri IS a feature of Gorlin syndrome.
- B. Multiple basal cell carcinomas ARE the hallmark of Gorlin syndrome.
- C. Multiple OKCs ARE a diagnostic feature of Gorlin syndrome — they are often the first manifestation.
- D. MISSING (absent) clavicles are a feature of CLEIDOCRANIAL DYSPLASIA — NOT Gorlin-Goltz syndrome. Gorlin-Goltz (Basal Cell Nevus) syndrome features: multiple basal cell carcinomas, odontogenic keratocysts (OKC), calcification of the falx cerebri, bifid ribs, skeletal anomalies, and macrocephaly. The clavicles are NOT typically absent in Gorlin syndrome.
