Papillary carcinoma of the male breast: report of a case

Intracystic papillary carcinoma of the male breast represents an extremely rare entity that accounts for less than 1% of all malignancies, and histologically may range from papillary hyperplasia in gynecomastia to invasive papillary carcinoma. This report presents the case of a 61-year-old Caucasian man who presented with a 5-year history of a centrally located painless swelling of his right breast with occasional nipple discharge. Triple assessment was very helpful in establishing the diagnosis. Treatment included a mastectomy and hormonal therapy because the neoplasm expressed hormone receptors. Although male breast carcinomas tend to behave more aggressively than their female counterparts, the prognosis of this neoplasm is excellent.
