We report the case of a 24 year old woman, without significant past medical history, who consulted for an asymptomatic and pigmented lesion of the breast evolving from infancy. Dermatological examination showed a brown plaque localized on the milk line in the underside of the right breast, measuring 1 cm, firm in consistency, with a non infiltrated base. Dermoscopic examination revealed a peripheral pigmented regular network with a cleft-like appearance in a pigmented homogeneous central area. The rest of clinical examination was normal. Based on the clinical and dermoscopic findings a diagnosis of supernumerary nipple was established. The patient refused the removal of the nipple since it was asymptomatic and without any aesthetic concern.
