Out of our 39 early carcinoma cases of the colon, 34 cases, on whom barium enemaexam was done before operation, are divided into 4 groups, i.e., pedunculated, semipedunculated, sessile and ulcerative ones. To begin with, the correlation between size and invasion of carcinoma is studied. And existencediagnosis is discussed, and thereafter qualitative diagnosis is also discussed.<BR>We have compared our 34 early carcinoma cases with 59 benign polyp ones. With regard to the group, in pedunculated ones, differencial diagnosis is difficult because of no relations between them, but in semipedunculated and sessile ones, differential diagnosis is rather easy because of their different sizes. The uneveness of the surface has correlation with histologic findings, but it has no connection with differential diagnosis between malignancy and benignancy.<BR>With regard to the depth of invasion, the correlation between early carcinoma cases and 23 advanced carcinoma cases (protruding type) is discussed: Almost all cases of the pedunclated type are carcinoma in situ. The sessile cases more than 25 mm in size are advanced and almost all cases that make ulcer on their surface are also advanced.<BR>In the conclusion, it is very important to delineate the surface of the lesion mimutely.
