GlossaryTrichoepithelioma

benign skin tumor originating from hair follicles

Trichoepithelioma is a benign skin tumor that originates from hair follicles. It typically appears as small, firm, flesh-colored or slightly pink nodules, often on the face, and is usually non-cancerous. While it is generally harmless, multiple lesions can sometimes be associated with genetic conditions, and a dermatologist may perform a biopsy to confirm the diagnosis.
