  • Abstract
  • Look Inside

 A 77 year-old woman, who had been given radiation therapy for a carcinoma of the cervix 25 years before, was referred to the Saitama Cancer Center with diarrhea in October 1984.

 Colonoscopy revealed a reddened sessile lesion at 15 cm from the anal verge (Figs. 1 a and b). A barium enema examination demonstrated a flat polypoid lesion of 9 mm in diameter in the rectosigmoid (Figs. 3 a and b). After a segmental resection of the rectum, the lesion was revealed to be a plaque-like nonulcerated Type Ⅱa carcinoma of 8 × 5 × 0.2 mm in size (Figs. 4 and 5), and was histologically diagnosed as well differentiated adenocarcinoma in the propria mucosa without evidence of adenomatous glands (Figs. 6 a and b). This carcinoma was considered to have arisen de novo rather than from a preexisting adenomatous polyp since such a preexisting polyp could have hardly been destroyed completely by the tiny carcinoma found in our patient. We emphasize that not only colonoscopy but double contrast barium enema as well is useful for detection of early colon carcinomas.
