A hypoechoic, partially non-echoic mass was observed by EUS and EUS-FNA was performed, but pathological diagnosis could not be made. Gastrointestinal stromal tumor was suspected, and Laparoscopy and Endoscopy Cooperative Surgery was done. Pathological examination was observed dense growth of spindle-shaped cells. Immunohistochemical staining were S100 (+) , CD117 (-) , CD34 (-) , desmin (-) , so it was diagnosed gastric schwannoma.
