Abstract
A 74-year-old man was admitted to our hospital with complaint of the abdominal tumor. A diagnosis of malignant lymphoma of the stomach was made by barium meal, endoscopic examination and direct-vision brushing cytology of the lesion. EUS findings showed that the five-layer structure of the gastric wall was destructed by hypoecohic homogeneous tumor. This findings suggested that the lymhoma invated into the serosa. After chemotherapy the 3rd and 4th layer of the gastric wall were re-visualized by means of EUS, therefore the invasion of lymphoma was thought to become limited to the mucosa. It is rare that the reduction of intramural infiltration of gastric lymphoma was observed by EUS.
