Pathology

Breast papilloma is a term that describes an intraductal papillary configuration of the mammary epithelium on macroscopic or microscopic examination. It includes solitary intraductal papillomas, multiple papillomas, papillomatosis, and juvenile papillomatosis (JP).1

 

Polypoid fibrovascular tumors that are covered by benign ductal epithelium and that arise in the ducts of the breast.

 

A pedunculated proliferation of duct epithelium that generally arises within 1 cm of the areola and rarely is greater than 5 mm in size. The associated duct is generally dilated. The epithelium is friable with a delicate villus structure made up of fibrovascular tissue covered by epithelial cells. Intraductal papilloma is difficult to differentiate from papillary carcinoma, especially on frozen section.
