Erosive adenomatosis of the nipple: Conservation of nipple by Mohs micrographic surgery.

Erosive adenomatosis of the nipple (EAN) is a rare, benign tumor that resembles Paget's disease and well-differentiated adenocarcinoma. Total excision of the nipple has been the usual treatment modality because of the high incidence of recurrence when removal is incomplete, and complete excision generally mandates a reconstructive procedure. We report a case of a 56-year-old woman with EAN treated with Mohs micrographic surgery (MMS). We suggest that MMS is the first choice of treatment for EAN because it can be effectively used to remove the tumor completely and at the same time preserve the nipple, if performed early enough, before the tumor is widely spread.
