A prolapsed intraductal papilloma: a case report.

Intraductal papillomas (IP) are benign papillary lesions caused by proliferation of mammary ductal epithelium. IP occurs in the breast tissue. Prolapse of IP from nipple can be rarely seen. IPs are generally treated with total excision. A 31-year-old female patient was admitted to our clinic because of a protruded lesion from the nipple of her right breast. On her breast examination, an 8 mm- prolapsed mass was seen on the areola of her right breast. Breast ultrasonography showed no other lesions in the breast. The patient was operated with initial diagnosis of IP. The prolapsed mass, the overlying nipple skin and related ductus were totally excised under local anesthesia. Histopathological examination of the specimen revealed intraductal papilloma without atypical dysplasia. Herein, we are presenting a rarely encountered case of IP prolapsed from the nipple of a female patient.
