A case of desmoplastic trichilemmoma / 대한피부과학회지

ABSTRACT

Desmoplastic trichilemmoma is a rare variant of trichilemmoma. A 46-year-old woman presented with a verrucous papule on the face. Histologically, well-circumscribed lobular growth with abundant central desmoplastic stroma was seen. Peripheral area of tumor lobules showed the usual feature of trichilemmoma, whereas the center of tumor was replaced by irregular cords and nests of basaloid or malpighian cells entrapped in a dense stroma, mimicking invasive carcinoma. It was diagnosed desmoplastic trichilemmoma by the distinctive histologic appearance and totally excised.
