A 22-year-old man underwent an FDG PET/CT scan to evaluate possible malignancy due to melena and fever for 1 month. The images demonstrated intense FDG activity with an SUVmax of 24.6 in a large mass in the fundus of the stomach. Gastric malignant fibrous histiocytoma was histopathologically confirmed. Malignant fibrous histiocytoma is a high-grade and aggressive sarcoma, which usually occurs in the limbs or retroperitoneum. Malignant fibrous histiocytoma in the stomach is rare.
