[1] Other conditions that have similar symptoms and signs as nipple adenoma include Paget's disease of the breast, other intraductal papillomas, ductal carcinoma in situ (DCIS), syringomatous adenoma of the nipple and subareolar sclerosing duct hyperplasia.

Nipple adenomas usually have a rounded outline at low magnification, and at higher magnification can be seen to consist of a haphazardly arranged mass of proliferating tubular structures composed of epithelial and myoepithelial cells within varying amounts of fibrous stroma.

[1] The appropriate treatment in contemporary western medicine is complete surgical excision of the abnormal growth with a small amount of normal surrounding breast tissue.
