An unusual rectal carcinoma. A case report.

The case history of a patient whose barium enema radiographs confirmed the clinical diagnosis of a stenosing rectal carcinoma is presented. Two years previously, the patient had undergone sub-total gastrectomy for carcinoma of the gastric antrum. An abdominoperineal excision of the rectum was performed, and histological examination of the tumour showed it to be not primary large bowel in origin, but a metastatic manifestation of the original gastric cancer.
