 note = {Case 1 (a 53-year-old man, postoperative status for hepatocellular carcinoma, follow-up of 1.5 years) developed anal pain on defecation. A barium enema showed a segmental stricture. Colonoscopy revealed a multinodular mass with no obvious ulcer 4 cm from the anal verge. Endoscopic ultrasonography showed a mucosal mass with a preserved layer structure of the rectal wall. A biopsy of the lesion showed the characteristic features of fibromuscular proliferation in the lamina propria. He underwent a colostomy because of rectal stricture. He remained asymptomatic after the colostomy. Case 2 (a 54-year-old man, postgastrectomy status for gastric carcinoma, follow-up of 10 months) presented with thin stool and rectal pain on defecation. A barium enema revealed a segmental stricutre. Colonoscopy showed a multipolypoid mass with no ulceration 5 cm from the anus. A pelvic CT scan showed a mucosal mass with a normal layer structure of the rectal wall. The bioptic findings were identical to those of Case 1. He also underwent a colostomy and showed a good recovery. The two above described patients were both misdiagnosed to have rectal carcinoma, especially linitis plastica on the colonoscopic appearances. A biopsy of the lesion may lead to an accurate diagnosis of mucosal prolapse syndrome. A colostomy is thus considered to be a useful alternative treatment as a temporary strategy for such patients., 論文},
