A Case of Squamous Cell Carcinoma Arising in Nevus Sebaceus / 대한피부과학회지

ABSTRACT

In adulthood, nevus sebaceus is frequently associated with the development of a number of benign and malignant neoplasms. Basal cell carcinoma is known to be the most frequent malignant tumor arising in nevus sebaceus, while squamous cell carcinoma is a rare complication of nevus sebaceus. Herein, we report a 42 year-old man who had a slightly tender, 0.6 X 0.6cm sized, erosive papule in a 1.0 X 3.5cm sized, linear nevus sebaceous on the right parietal scalp. The histopathologic examination showed invasion of the dermis by epidermal masses with many horn pearls. The tumor was excised with 1.5cm margins and there has been no recurrence for 5 months.
