Case: H. I. a 61-years old male.In May 1972, he was admitted to Mitoyo general hispital for health survey.Several cherry-sized negative shadows were observed on the antrum by X-ray and subsequent endoscopic study revealed localized swelling of mucosal folds and several oval protrusions with central depression. These findings suggested erosive gastritis, and the patient was followed up by repeating X-ray and endoscopic examinations four times during about five years. In June 1977, he noticed hunger pain in the epigastrium for the first timt. The final X-ray and endoscopic examination revealed a deep ulceration on the lesser curvature of pyloric region. The margin of the ulcer was elevated nodularly and malignant change was suspected, but biopsy demonstrated no maligmant cells. Gastric resection was done including extirpation of second regional lymphnode group. Histologically reactive lymphoreticular hyperplasia of high degree was seen in the antrum. Sarcoma cells localized in the mucosa and submucosa near the deep ulcer were come in contact with the reactive lymphoreticular hyperplasia, and regional lymphnodes were free of malignancy. From these findings, this case was diagnosed as primaly early gastric reticulum-cell sarcoma associated with reactive lymphoreticular hyperplasia.
