A 69-year-old woman who had vomited blood underwent abdominal enhanced computed tomography (CT) examination, which identified a gastric submucosal tumor. On upper gastrointestinal endoscopy, the tumor was found at the anterior wall of the lower gastric body. Arterial bleeding was seen from the tumor surface, but endoscopic hemostasis was unsuccessful. Therefore a distal gastrectomy was performed to enable hemostasis. Histopathological findings confirmed the diagnosis as gastrointestinal stromal tumor (GIST) of the stomach. In cases of gastrointestinal bleeding from tumors which are resistant to endoscopic hemostasis, it is necessary to perform other treatments such as surgery.
