Metastases to the breast from extramammary primaries are uncommon and account for 0.5–6% of all breast malignancies (Georgiannos et al., 2001, and Vizcaíno et al., 2001). Malignant melanoma, lymphoma, and lung and gastric carcinomas are the most frequently encountered nonmammary metastases to the breast in adults (Georgiannos et al., 2001, and Chaignaud et al., 1994). Primary colorectal adenocarcinoma (CRC) metastatic to the breast is extremely rare, with the medical literature having only 19 recorded cases. Typically CRC metastatic to the breast is indicative of widely disseminated disease and a poor prognosis. Here we present a case of poorly differentiated colon cancer metastatic to the breast and review the current literature on this rare event.
