A 60-year-old man was admitted to our hospital in a state of shock caused by hematemesis. Emergent endoscopic examination revealed a deep ulcer at the greater curvature of the gastric body and a cavity at the bottom of the ulcer. Computed tomography showed a giant cystic lesion reaching the pelvic cavity, and Gastrografin retention in the mass suggested connection with the stomach. Angiography showed that the tumor was supplied by the left gastric artery and was hypervascular with tumor stain. Total gastrectomy, distal pancreatomy and splenectomy were performed. The resected specimen was 29×16cm with giant central necrosis. Histological and immunohistochemical studies showed that it was negative for vimentin and S-100 protein, and positive only for CD 34. Therefore, this tumor was identified as a stromal tumor, uncommitted type.
