A Case of Congenital Trichofolliculoma / 대한피부과학회지

ABSTRACT

Trichofolliculoma is a benign, highly structured adenoma of the pilosebaceous unit, usually occuring on the face or scalp as 0.5 to 1.0 cm solitary papule in persons past middle age. This benign neoplasm rarely occurs prior to early adult life or neonate. We report a case of congenital trichofolliculoma in a 13-year-old girl who had had a single asymptomatic mass on the posterior aspect of right auricle since birth.
