Erosive adenomatosis of the nipple in an eight-year-old girl.

Erosive adenomatosis of the nipple (EAN) is a rare, benign neoplasm of breast lactiferous ducts. Peak incidence is in the fifth decade in women. Clinically, it may be mistaken for Paget's disease and, histologically, for adenocarcinoma. Some authors have proposed an association with breast carcinoma and fibrocystic breast changes. Erosive adenomatosis of the nipple is extremely rare in children. Treatment is usually local excision of the nipple. This is the first formal English language case report of EAN in the pediatric age group. It is important for dermatologists to be familiar with this entity to prevent unwarranted breast removal.
