title: Rectal carcinoma metastasizing to the breast: a case report and review of literature.
abstract: Extramammary breast metastases (from non-breast primaries) are rare, constituting only about 2% of all breast metastases, although autopsy studies show that it may occur in up to 6% of cases. Lymphoma, metastatic melanoma, and bronchial carcinoma are the malignancies that account for the majority of breast metastases. Breast metastases from a colorectal carcinoma have been described in only a small number of cases in the literature. We present a case of a 42-year-old woman with an incidental finding of a breast lump. She had a history of Dukes C rectal carcinoma for which she had undergone an anterior resection 11 months earlier. The breast deposit was the first clinical indication of relapse. The patient subsequently developed liver and brain metastases and deteriorated rapidly; she died 2 months after presenting with the breast mass.
