Erosive Adenomatosis of the Nipple / 대한피부과학회지

The patient was a 35 year old woman complaining of non tender erythematous nodule on the left nipple for 2 years. Histopathologic findings showed focal acanthosis and extension of epithelium into some of the superficial ductal structures. In the dermis, the tubules were lined by a peripheral layer of cuboidal cells and a inner layer of columnar cells. The papillary projections of the luminal cells into the lumen also were shown. In the upper dermis, we could find the keratin cysta. She was treated with a simple excision of the nipple and subareolar tissue.
