We have observed twelve cases of unusual acute ulcers in the corpus of the stomach. These ulcers showed characteristic shapes, by fluoroscopy, endoscopy and specimens of resected stomachs, which were wide superficial and irregular shapes such as trench, map-like or tongue-like, and it was often difficult to distinguish from them to the depressed early gastric cancer, . The patients had been accopanied with severe clinical symptoms which were heavy epigastric pain, hematemesis and melena etc. They were nine male and three female in sex, ranging from twenty-six to seventy-three old-year in age. And they were almost hospitalized as an emergency because of these severe clinical symptoms. Three cases were operated under diagnosis of suspicion of malignancy that was early gastric cancer, IIc or IIc+ III. Histologically they were wide, superficial and shallow ulcers, so clled Ul-II, except for a bit of area that was so c.lled Ul-III. Stress had been suggested as an inducement in six cases, drugs in two cases, repeated vomitings in one case, but unknown in three cases. Though it would be thought that stress, drugs and vomitings induced these ulcers, we had no experiences of these types in stress-induced ulcers, drug-induced and vomiting-induced, too. Now the pathogenesis of gastric ulcer has not been obscure, so it is more difficult that we investigate the genesis of these cases. But, if allowed, it would be supposed that the diturbance of regional blood flow in the corpus might be related to these ulcers because they were rare shapes in the limited area.
