A 65-year-old man underwent total cystectomy in 1972 for a bladder tumor. Ureterosigmoidostomy was performed in this case. A physical examination in 1983 revealed occult blood in the feces, and colon fiberscopic examination disclosed a polyp in this patient, who then underwent polypectomy. Histology confirmed hyperplasia. In 1985, colon fiberscopic examination revealed a polyp in the sigmoid, resulting in another polypectomy. Adenoma was established by histology. In April 1991, fresh blood was found in the feces, and a Borrmann II tumor was confirmed by colon fibrerscopic examination. Sigmoidectomy, colostomy, and right ureterostomy were performed. Histology confirmed moderately differentiated adenocarcinoma.
