title: The nevoid basal cell carcinoma syndrome. Histopathology of the basal cell tumors.
abstract: 126 basal cell carcinomas from 7 patients with nevoid basal cell carcinoma syndrome were examined histologically and--using a scoring system--compared with 54 solitary basal cell carcinomas. The solid subtype formed 78.9% of all tumors in the head and neck region and 48.9% of those located elsewhere. A broader spectrum of histological subtypes was noticed in tumors from patients with the syndrome. As multiple, keratinizing odontogenic and epidermal cysts are often seen in the nevoid basal cell carcinoma syndrome it was interesting to see that multiple keratinizing cysts within skin tumors were recorded more often in this group.
