[Late solitary metastases of breast origin presenting as primary colonic carcinoma].

The case of a 72-year-old woman with 2 solitary metastases to the colon of breast origin with mimicked primary colonic cancer is presented. The primary breast lesion was an infiltrating duct carcinoma and the metastases to the colon were discovered 6 years later. Some of the regional lymph nodes draining the colon were infiltrated by tumor, probably originating from the 2 colonic metastases. This is an unusual condition that has not as yet yet been reported.
