Abstract
A 75-year-old woman had bloody stools and pain around the anus for a long time. After a detailed examination, anal canal adenocarcinoma with pagetoid spread was diagnosed. The rectum and anal canal were very narrow due to the cancer and its infiltration to surrounding tissue. Thus, the patient had a temporary double-barreled colostomy to rest the bowel ; the cancer site was irradiated prior to an abdomino-perianal resection. In advance of the operation, the resection range was determined by mapping biopsy. On histopathology, no tumor cells were found in the specimen ; the patient has been well and disease-free for 9 month after surgery.
This very rare tumor case appears to have benefitted from pre-operative radiation. Thus, we report on this effective approach along with a review of the literature.
