Granular cell tumors are usually found in the skin, tongue or breasts. They seldom originate in the gastrointestinal tract, especially in the stomach. A case of granular cell tumor in the stomach which we experienced is described in this report. The patient was a 58-year-old male. His chief complaint was precordial pain. A Yamada type II polpoid lesion with a smooth surface, a dimple in the center and bridging folds located in the greater curvature of the middle body of the stomach was detected by upper gastrointestinal roentgenography and endoscopy. It was diagnosed as a submucosal tumor based on endoscopic ultrasonographical finding. A gastrectomy was performed because of the possibility of malignancy. The cut surface of the tumor measuring 20×15×15 mm was yellowish-white. Histologically it was diagnosed as a granular cell tumor.
