  Trichoadenoma is an exceptional, benign, cutaneous adnexal neoplasm engendered from the hair follicle, particularly infundibular portion of pilo-sebaceous unit. The neoplasm was initially scripted by Nikolowski and described as an “organoid follicular hamartoma” in 1958. Trichoadenoma chiefly represents an abortive, mature differentiation towards hair follicular structures. Currently, trichoadenoma is considered as a histological enigma although immune histochemical evaluation indicates morphological differentiation towards a distinctive follicular neoplasm [1].
