[A case report of early rectal carcinoma, IIa + IIc type, with no invasion of the submucosa].
A 66-year-old woman was admitted to the Hakodate Chuo Hospital because of abdominal discomfort. A barium enema study revealed a deformity of the middle Houston's valve of the rectum and granular lesions at the Rb region of the rectum. A colonoscopic examination showed the IIa + IIc type of early rectal carcinoma. A resected specimen also revealed IIa + IIc type early rectal carcinoma, 8 X 13 mm in diameter, and well-differentiated adenocarcinoma with no invasion of the submucosa. Infiltration into the lymphatic vessels and regional lymph node metastasis were not encountered. The deformity of the rectal Houston's valve was checked by a barium enema study. It should be emphasized that early detection of colorectal carcinoma with no invasion of the submucosa, requires careful barium enema studies and colonoscopic examination.
