Erosive Adenomatosis of the Nipple

Abstract

Erosive adenomatosis of the nipple is a rare benign neoplasm caused by a complex proliferation of the lactiferous ducts that affects primarily middle-aged women. Clinically, the differential diagnosis is breast carcinoma, Paget disease, and galactophorous dilatation. A correct diagnosis is fundamental to avoid unnecessary major surgery, which can increase treatment morbidity and harm the patient.
