[Adenoma of the nipples. A rare, but essential differential diagnosis]

A case is presented, where a 52 year-old woman with a two month history of nipple discharge was diagnosed with adenoma of the nipple. A total excision of the nipple was performed. Adenoma of the nipple is a rare, but benign condition, which clinically can be confused with Paget's disease of the nipple, intraductal papilloma and adenocarcinoma of the breast. Complete excision of the nipple is an adequate treatment of this condition.
