title: Large basal cell carcinoma in a congenital nevus.
abstract: A large basal cell carcinoma that developed in a previously irradiated congenital nevus is reported. Treatment was by wide surgical excision. A discussion of the possibility that congenital nevi may predispose to tumors other than melanoma is considered. The causes of basal cell carcinoma are reviewed.
