title: Ductal carcinoma of the breast metastasizing to the rectum.
abstract: Gastrointestinal metastasis of the breast cancer is rare and its management varies significantly from that of a primary bowel cancer. We report a case of invasive ductal cancer metastasizing to the rectum and masquerading as a rectal primary. A 60 year old caucasian woman presented with fresh rectal bleeding nine years after treatment of her primary breast cancer. The investigations revealed features suggestive of primary rectal malignancy and was managed accordingly. However, the surgical histopathology revealed poorly differentiated metastatic adenocarcinoma and the immunohistochemical evaluation confirmed origin from a breast primary. She had an uneventful post-operative recovery and remains disease free thus far. The continuing advancement in the management of breast cancer patients with resulting increase in the overall survival will lead to such unusual metastatic presentations. Hence, the awareness, identification and differentiation of such rare metastatic presentation are important in order to manage the patients appropriately in the future.
