Colonic metastasis of breast carcinoma.

Metastasis of breast carcinoma to the colon is a rare occurrence. We report here the case of a 65-year-old patient who presented a stenosing tumor of breast origin, located in the right colon. Some of the regional lymph nodes were infiltrated but no distant metastasis were detected. The primary breast lesion was a 4-cm infiltrating adenocarcinoma, operated 4 years earlier. Surgical removal of the lesion was followed by Endoxan-Epirubicin and 5-Fluororacil chemotherapy and the patient remained disease-free during the 3 years of follow-up. We could find only 2 similar cases reported in the world literature until now. Profound anemia in a patient with a past history of breast carcinoma may indicate colonic metastasis; treatment should be surgery followed by chemotherapy.
