Histopathological and immunohistochemical studies of a typical case of intraductal papillary carcinoma of a male breast

Breast carcinoma in men is extremely rare; it represents 0.6% of all breast carcinomas and less than 1% of all malignancies in men [1]. Intraductal papillary carcinoma (IPC) is also a rare form of breast cancer, accounting for 0.5–1% of all breast cancers [2]. IPC in man is an extremely rare disease with only very few case reports published in the literature so far [3-5]. IPC accounts for 5 to 7.5% of all male breast cancers [6]. It typically occurs at an old age with a good prognosis [7]. Intraductal papillary carcinoma is a rare form of malignant breast disease, which constitute about 0.5% to 1% of all breast cancers.
