Nipple Adenoma (NA) is a very uncommon, benign proliferative process of lactiferous ducts of the nipple first described by Jones in 1955. Clinically, it often presents as a unilateral and asymptomatic palpable nipple nodule, a visible nipple skin erosive lesion, and/or with discharge from the surface of the nipple skin. It is primarily seen in middle-aged women. Nipple adenoma can clinically mimic a mammary Paget’s disease of the nipple [1]. The gold standard for making the most definitive final diagnosis of NA is histopathologic examination which shows a benign proliferation with a double cell component made up of bordering epithelial cells and peripheral myoepithelial cells [2]. Rare observations in the literature have focused on the interest of dermoscopy in the positive diagnosis of NA, dermoscopic signs are structureless red areas and pink-white clods correspond to erosion and interspaced epidermis in histopathology, respectively. Red dots in linear, radial, semicircular patterns correlate with tubular and luminal openings in histopathologic studies. Red globules and red lines correspond to regular vessels of a benign tumor [3]. The treatment of choice for this pathology is that which ensures complete excision of the lesion and allowing plastic reconstruction of the nipple [1]. We describe a new case of dermoscopy of a Nipple adenoma.

A 34-year-old woman presented with a 2-year history of a nodular lesion on the right nipple, clinical examination showed a well-limited 5mm nodule with eroded and hyperkeratotic surface. Dermoscopic examination revealed, pink-white clods, red dots with pink background and yellow hyperkeratotic scales. Histopathologic study was compatible with NA.
