A Case of Sebaceous Adenoma / 대한피부과학회지

ABSTRACT

Sebaceous adenoma is a benign organoid tumor of proliferating, incornpletely differentiated sebaceous glands. We report a case of sebaceous adenoma in a 15-year-old male. He had a 1.7 x 2.2 cm sized, asymptomatic, srnooth, round, raised, firm, reddish tumor on the left quadrant of abdomen. Histopathologically, the tumor was composed of lobules of irregular size and shape, and sharply demarcated from the surrounding tissue, The most lobules showed undifferentiated germinative and mature sebaceous cells in about equal number. Sebaceous cells in lobules were stained for prekeratin by means of avidin-biotin-peroxidase complex method. Ten months after surgical excision there was no evidence of recurrence.
