Gorlin's syndrome, or nevoid basal cell carcinoma syndrome.

Gorlin's syndrome is a condition inherited in an autosomal dominant fashion. It involves many organs, but principally affects the skin, skeleton, and endocrine and nervous systems. The most common features are multiple nervi and basal cell carcinomas of the skin, benign jaw cysts, dyskeratotic pits in the palms and soles, rib and vertebral abnormalities, brachymetacarpalism, and calcification of the falx cerebri. In 14 patients, 4 of whom belonged to one family, the age at the time of diagnosis ranged from 11 to 63 years. Ten patients are alive, but five are severely disfigured by carcinomas. Two patients died of complications resulting from uncontrolled tumours, and two died of other cancers. New skin tumours constantly develop; small ones can be excised, but large ones require extensive surgery with or without radiotherapy.
