A retrospective study was made in the 243 patients with early gastric carcinoma resected during thr last 12 years as to if there were any endoscopic characteristics closely related to the types of histology. I. Protruded and/or elevated type (77 lesions). Predominant type of histology in the polypoid cancer (I, ha, I+IIa, IIa+I) was well differentiated tubular adenocarcinoma, while in the particular type of polyps associated with IIc at the base were poorly differentiated. In the circularly or hemicircularly protruded types (IIa+IIc), the types of histology depended on the steepness of protrusion and the depth of depression at the center. II. Depressed and/or excavated type (168 lesions).Close relationships were found between histological differentiations and endoscopic findings (characteristics of the margin, the floor of depression and/or excavation and shapes of the surrounding mucosal folds). III. Flat type (7 lesions). There were no endoscopic characteristics corresponding to the histological differatiaions. Further efforts must be made to obtain endoscopic and histological correlations in this particular type of early gastric carcinoma.
