A 50-year-old woman underwent an esophagogastroduodenoscopy, which revealed a 7 mm submucosal tumor on the greater curvature of the upper gastric body. A biopsy was performed and the tumor was diagnosed as a granular cell tumor (GCT). The patient was then referred to our hospital. Endoscopic ultrasonography revealed a homogeneous low echoic tumor in the 2nd-3rd layer. An endoscopic submucosal dissection (ESD) was performed and the tumor was resected en bloc. Histopathological diagnosis was a benign GCT. The treatment of GCT of the stomach is still controversial, because of its rarity. Malignant GCT of the stomach has been reported, so we must consider the removal of tumors. ESD could become a treatment option after preoperative detailed examination.
