Intracystic papillary carcinoma of the breast in a Nigerian male: case report.

Intracystic papillary non invasive breast carcinoma is an extremely rare form of intraductal carcinoma constituting 5% of male breast cancer. The latter accounts for only 1% of all breast cancers. Until now, no case has been documented in an African male. This tumour was found in an 86 year-old male. It appeared benign on physical examination. Fine needle aspiration cytology was inaccurate. However, excisional biopsy in the form of total mastectomy with axillary clearance served to diagnose as well as treat the disease. This may be the first case of intracystic papillary carcinoma of the breast in the Nigerian male.
