Abstract
- Erosive adenomatosis of the nipple is a rare, benign neoplasm, currently thought to originate from the terminal lactiferous ducts and subareolar breast tissue. Clinically, erosive adenomatosis of the nipple is often indistinguishable from that of mammary Paget's disease, and it could be misdiagnosed as intraductal carcinoma as it has a similar histological finding. We present the case of a 36-year-old woman who had a unilateral erythematous induration of the nipple that contained a palpable, firm nodule. It had first been noticed 2 years earlier. The surface was occasionally crusted, and there was a bloody discharge. Histopathological examination showed irregular, dilated tubular structures, which were lined by a peripheral layer of cuboidal cells and a luminal layer of the columnar cells that demonstrated decapitation secretion at their luminal border.
