Erosive adenomatosis represents a benign proliferation of the nipple in a middle-aged women.


Also known as papillary adenoma of the nipple, erosive adenomatosis may present with unilateral nipple erosion, discharge, or a mass in a middle-aged woman. The lesion is consistently superficial in location, unlike breast carcinoma. Histologically, one sees proliferating ductal structures lined by a double layer of columnar epithelium.


Simple surgical excision is appropriate with reconstruction if needed. Mohs surgery has been recommended.
