title: [A case of IIa + IIc type early carcinoma of the rectum, with no invasion of the submucosa].
abstract: A case of a IIa + IIc type early carcinoma of the rectum is reported. A 62-year-old man, who had been checked by immunological latex agglutination faecal occult blood testing, underwent a colorectal examination at Hakodate Chu-o Hospital. A barium enema revealed a slightly elevated lesion with a central depression in the lower rectum. Colonoscopic examination showed a IIa + IIc type of early rectal carcinoma. Study of the resected specimen also confirmed a IIa + IIc type early rectal carcinoma, 17 x 15 mm in diameter. Histologically, a lesion was located within the mucosa and consisted of both a carcinoma and an adenoma. Immunological latex agglutination faecal occult blood testing was thought to be useful for mass screening detection of a colorectal carcinoma.
