Abstract
A 57-year-old woman underwent an abdminoperineal resection for rectal cancer 14 yeas ago. The patient visited our hospital because of a gradually increasing tumor at the colostomy site. The tumor at the colostomy site measuring 4 cm had an irregular surface, and a biopsy indicated of adenocarcinoma, but a computed tomography (CT) scan suggested no metastasis. We performed a partial resection, including the stoma and the surrounding skin, and reconstructed a colostoma at the same place. She is still alive without recurrence, as of one year after the operation. Carcinoma rarely occurs at a colostomy site. We propose that we should conduct long-term follow up with patients who have undergone an operation for colo-rectal cancer and consider the facts case-by-case when we operate for adenocarcinoma arising at a colostomy site.
