Dermoscopy Case of the Month

Mammary Paget's disease is a rare intraepithelial carcinoma of the nipple/areola complex often associated with ductal breast carcinoma. We report a case of a 55-year-old female patient with a classical form of mammary Paget's disease associated ductal ipsilateral breast carcinoma. Dermoscopy of Paget's disease revealed a whitish-pink area with polymorphous vessels organized in irregular nests separated by pale streak-like structures, with peripheral light brown diffuse pigmentation. Dermoscopic features described in this case are in agreement with rare previous reports and may contribute to better differentiation of mammary Paget's disease from clinically similar lesions.
