title: Supervention of a pigmented basal-cell carcinoma upon a nevus sebaceus.
abstract: A case is reported of a deeply pigmented, pedunculated mass that developed upon a verrucous nevus. Biopsy proved the combined lesion to be a pigmented basal-cell carcinoma upon a nevus sebaceus. The carcinoma was completely contained in the biopsy and the nevus sebaceus it sprang from was ablated by surgical excision. Modern experience and management of such cases are reviewed briefly.
