Desmoplastic Trichoepithelioma: A case report

ABSTRACT

Desmoplastic trichoepithelioma is a solitary tumor of the hair follicle with female preponderance, most commonly located on the face. Clinically, the lesions appear annular and firm with a raised border and a depressed nonulcerated center, but the appearance is not so distinctive to hair follicle tumors that definite diagnosis is established by the histopathologic findings. We report a case of desmoplastic trichoepithelioma in a 67-year-old woman who had an asymptomatic, hard, annular lesion measuring 0.8 cm in diameter, with a raised border and a depressed center on the right cheek. Histopathologic findings showed narrow strands of basaloid cells, horny cysts, and desmoplastic stroma, with the features corresponding to the desmoplastic trichoepithelioma.
