Carcinomas rarely occur at the site of a colostomy. Colostomies are risk for malignancy, just as in any other portion of the colon. If the initial resection was for cancer, then the risk of metachronous colon adenocarcinoma is significantly higher than for the general population. Metachronous colorectal carcinoma occurs from 0.1 to 3.6 percent of patients who undergo surgery for colorectal carcinoma and the recurrence of the primary bowel malignancy that necessitated the stoma may present with signs of bleeding or obstruction. We report three cases of this rare neoplasia occurring at the site of a colostomy, and we review the literature.
Keywords : Metachronous colorectal carcinoma; colostomy; stoma complications.
