Supernumerary nipple in the dermoscopy: about a case

Abstract

We report the case of 40-year-old woman, followed for breast cancer, who consulted for an asymptomatic and pigmented lesion evolving since early childhood under the right breast. The dermatological examination showed a brown plaque, measuring 2 cm, of firm consistency, with a slightly infiltrated with nippled surface (A). Dermoscopic examination revealed a regular pigmented peripheral network with a cleft-like appearance in a pigmented homogeneous central area (B). A diagnosis of a supernumerary nipple was established. The patient refused to remove the nipple because it was asymptomatic and without any aesthetic concerns. However, we made the patient aware of the importance of self-monitoring and medical surveillance of the supernumerary breast, especially with the history of breast cancer. Supernumerary nipples are are; they can be associated with other malformations. Because of the possible morbid associations; some authors recommend systematic search of other malformations while others don´t consider them. Supernumerary nipple do not require any specific treatment. However, surgical excision may be indicated for aesthetic reasons or in case of doubt diagnostic. Dermoscopy has been rarely described in the literature. S. salim and all reported the same dermoscopic aspect observed in our patient, however, Takahiro KIYOHARA and all reported a supernumerary nipple dermoscopically mimicking atrophic dermatofibroma with Central white patch and peripheral delicate pigment network on dermoscopy.
