Usually the esophagoscopic findings of esophageal cancer have been classified into six types, such as the superficial type, the tumorous type, the ulcerated type, the tumorous type with infiltration, the ulcerated type with infiltration and the seriously narrow type. 714 cases of esophageal cancer have been examined in our clinic for past six years. 85% of them were the ulcerformed type. Some typical cases were shown in pictures. The endoscopic findings of the superficial type, which was suspected to be the cancer limited to the submucosal layer in its infiltration, were moreover classified into five groups. There were the elevated type (tumorlike protruded and flat-elevated), the flat type and the excavated type (slightly depressed and excavated). In Japan total number of the superficial type of the cancer was about 40 cases and in our clinic 11 cases. The elevated type was occupied in more than 50% of all cases.
