Invasive cribriform carcinoma of male breast: A rare histopathologic entity

Male breast carcinoma is a rare entity with an incidence of less than 1% of all breast cancer cases, and more than 90% of male breast cancers are invasive. All types of breast cancer seen in females are present in males, with the most common histological variant being infiltrating ductal carcinomas. However, invasive cribriform carcinoma, a rare type of invasive breast carcinoma, is extremely rarely seen in males. Here, we report a very rare case of invasive breast carcinoma in a male patient, with only three cases reported earlier.
