Abstract

Sebaceous trichofolliculoma is a rare benign tumor and represents a variant of trichofolliculoma. Up to now, only 5 cases of sebaceous trichofolliculoma were reported in Korea. It generally presents as a centrally depressed solitary tumor and occurs in areas rich in sebaceous lobules. Microscopically, it shows cystic cavities with or without keratin-filled portion and sebaceous lobules. The lobules are connected to the cystic wall. We report a case of infected sebaceous trichofolliculoma on the right cheek accompanied by a unilateral microtia in a 16- year-old man. The patient was treated with oral antibiotics and surgical excision. By summarizing 12 past cases, 6 Korean and 7 international, we have put together clinical features of Sebaceous trichofolliculoma.
