A rare clinical presentation of desmoplastic trichilemmoma mimicking invasive carcinoma

Abstract

Trichilemmoma is a benign neoplasm from the outer sheath of the pilosebaceous follicle. Desmoplastic trichilemmoma, a rare variant, is histologically characterized by a central area of desmoplasia that can clinically mimic an invasive carcinoma, requiring histopathological examination to define the diagnosis. © 2014 by Anais Brasileiros de Dermatologia.
