Abstract:
Trichofolliculoma is an adnexal tumor of hair follicle oriyin, considered to be of intermediate differentiation between a hair follicle nevus, a simple hyperolasia of the hair follicle, and trichoepithelioma, Which usually lacks mature hair follicles. Grossly the tumor usually appears on the head or neck as a 0.5 to 1.0cm solitary white to pearly papule, Many lesions show a cental pore, and occasionally woolly or cottony hairs may protrude from this pore. Histologically, trichofolliculomas are characterized by a central dilated follicle filled with keratin or hair. Radiating from this primary hair follicle are numerous secndary hair follicles of varying degrees of maturation. An organized fibro-vascular stroma surrounds these epithelial structure, giving it a well-defined nodular appearance. We presented here two case of trichofolliculoma with typical clnical and histopathological findings, one in a 65 year-old female and the other a 56 year-old males.
