Nevoid basal cell carcinoma syndrome: report of an aggressive case with ethmoid sinus invasion

Nevoid basal cell carcinoma syndrome, also referred to as Gorlin–Goltz syndrome, is a rare autosomal dominant disorder characterized by multiple basal cell carcinomas, jaw cysts, palmar or plantar pits, ectopic calcification of the falx cerebri, and various skeletal developmental abnormalities. A minority of basal cell carcinomas demonstrate aggressive behavior and involve the craniofacial bones in nevoid basal cell carcinoma syndrome. A non-familial case of nevoid basal cell carcinoma syndrome with a basal cell carcinoma of the eyelid invading to the ethmoid sinus is reported.
