　A depressed lesion on the anterior wall of the corpus was diagnosed as of early gastric cancer based on the x-ray as well as endoscopic findings, although biopsy was negative for cancer. In addition to swelling and thinning of the mucosal folds with their abrupt cessation and worm-eaten state, the irregular shape of the depression with granular unevenness of its base and islet-like mucosal picture were typical of Ⅱc type early cancer.

　The diagnosis remained the same even after the gross observation of the resected stomach, but histologically no malignancy was found; it was a benign ulcer simulating a malignant one.
