Gorlin-Goltz syndrome: Multiple cutaneous basal cell carcinomas, odontogenic keratocysts of jaw, palmar and plantar pits, rare medulloblastomas, and skeletal abnormalities

Scanning magnification view of a cutaneous keratocyst shows an undulating squamous epithelium lining the irregularly shaped cystic spaces. There are no associated sebaceous glands, unlike steatocystoma.

The cyst shows a bland, multilayered squamous lining surrounding an irregularly shaped cystic space.

High-magnification view of the lining of the cyst shows a bland, multilayered squamous epithelium with a dense eosinophilic cuticle


Another high magnification of a cutaneous keratocyst shows a bland squamous epithelium with a dense eosinophilic, jagged-appearing cuticle

ETIOLOGY/PATHOGENESIS
Genetic
• Most cases are associated with NBCCS (Gorlin-Goltz syndrome: Multiple cutaneous basal cell carcinomas, odontogenic keratocysts of jaw, palmar and plantar pits, rare medulloblastomas, and skeletal abnormalities)
Mutations for NBCCS in PTCH1 gene on chromosome 9q22.3-q31, which encodes receptor for the Sonic Hedgehog signaling pathway
