Decoding Trichoepithelioma: The Hair Follicle Tumour Enigma

Trichoepithelioma is a benign adnexal skin tumour arising from hair follicle structures. It typically presents as small, firm, skin-coloured papules on the face, often in a familial pattern. While benign in nature, it may mimic basal cell carcinoma clinically and histologically, necessitating accurate diagnosis. Advances in dermoscopy and histopathology have improved differentiation, and management ranges from observation to surgical excision depending on the lesion's extent and cosmetic concern.
