A Case of Desmoplastic Trichoepithelioma / 대한피부과학회지

ABSTRACT

Desmoplastic trichoepithelioma is a rare benign adnexal tumor with female preponderance, most commonly located on the face. Clinically, the tumor measures from 3 to 8mm in diameter, and has a raised, annular border and a depressed nonulcerated center. The three characteristic histologic features are narrow strands of tumor cells, horn cysts, and a desmoplastic stroma. We report herein a case of desmoplastic trichoepithelioma in a 25-year-old woman who had an asymptomatic hard annular nodule with a raised border and depressed center on the left cheek.
