Gastric schwannomas are very rare mesenchymal tumors that can occur throughout the gastrointestinal tract, but are most commonly found in the stomach. The majority of patients have no symptoms, while others may complain of epigastric pain or upper gastrointestinal ulcer bleeding. Endoscopic examination of a gastric schwannoma commonly reveals a protrusive mass, but, as in this case, many types of ulceration can be observed with central necrosis. We report on a 62-year-old woman with endoscopic findings of 1 cm sized necrotizing ulceration and an 11 cm sized submucosal mass on radiological examinations. The patient underwent a wedge-shaped resection of the stomach and segmental resection of the transverse colon. Both histological and immunohistochemical staining revealed a gastric schwannoma.
