 A 51-year-old man visited our hospital in June, 1985, because of hematemesis. Upper gastrointestinal endoscopic examination showed a protruding and semispherical lesion with clear boundary and smooth surface in the posterior wall of the middle body of the stomach. There was, however, no bleeding. A small ulcer was observed at the center of the lesion. Since nausea, fatigue and anorexia continued, he was admitted to the hospital on July 10. Upper gastrointestinal x-ray examination demonstrated the protruding lesion with a small depression in the middle body of the stomach. The lesion was accompanied by bridging folds. Subsequently performed endoscopic ultrasonography showed a mass, 2 cm in size, clearly demarcated and with low echoic homogeneous contents in the 3rd layer. The 4th layer was intact. Based on these findings the mass was diagnosed as submucosal tumor. Considering a possibility of malignancy, gastrectomy was performed. The tumor measuring 20×18×16 mm in size was yellowish-white. Histologically it was granular cell tumor. Postoperative course was uneventful and he was discharged on August 28.

 The granular cell tumor rarely occurs in the gastrointestinal tract, especially in the stomach. As far as we know, this is the 8th case in Japan. All these cases reported were non-malignant.
