The two cases of the gastric lymphoid hyperplasia who-se diagnosis was initially made by biopsy were followed up. The first case was a 62-year old woman. On the first endoscopic examination mucous membrane showed uneven surface with erosions all over the stomach. In the cardia a large round tumor was observed. The histologic findings of lymphoid hyperplasia were obtained in all of the biopsy specimens taken from those lesions. But after three and half years, the findings of lymphoid hyperplasia disappe-ared at the lower half of the stomach, and there was only fibrosis. During the course, there were no suggestive findi-ngs shifting to sarcoma or to carcinoma. The second case was a 65-year old woman. A relatively shallow ulcer surrounded with widespread uneven mucous membrane was found from posterior wall to greater curv-ature of pyloric antrum. After three months, the ulcer healed to scar, and the biopsy specimens from the lesions did not show any findings of the lymphoid hyperplasia.
