An endoscopic examination for the upper gastrointestinal tract revealed multipleulcerated submucosal tumors all aver the gastric body, especially at the greater curvatureaspect. These features were compatible with those of metastatic gastric tumors. It was not u.ntil the autopsy revealed 4 months later that the primary site was the softtissue in the left femur and pathological diagnosis was made as malignant fibrous histiocytoma (MFH) -storiforrn-pleomorphic type with the metastases to multiple organsincluding the stomach. While MFH is common among the soft tissue tumors in the middle aged patents, 1thas been rarely reported as either the primary or the metastatic site in the alimentary itract.
