Intracystic papillary carcinoma in a male breast following mastectomy for infiltrating ductal carcinoma.

摘要

Male breast carcinoma accounts for less than 1% of all malignancies in men and represents 0.6% of all breast carcinomas. Intracystic papillary carcinoma (IPC) comprises 5% to 7.5% of all male breast cancers. We report a very unusual case of mammary IPC occurring in an elderly man following mastectomy for invasive ductal carcinoma, not otherwise specified (NOS).
