Leiomyosarcoma of the stomach are infrequently encountered tumors. They represent 1 to 3 percent of all gastric neoplasmas, and despite advances in endoscopy and computerized tomography, early diagnosis is rarely accomplished. A 38-year-old man presented with an upper abdominal tumor. Physical examination at admission showed that the tumor had a smooth surface and exhibited fluctuation. In upper gastrointestinal tract study (barium, endoscopy) revealed submucosal tumor with ulceration in the fundus. Computerized tomography and ultrasonography revealed a large cystic lesion with septums, compressing the stomach and pancreas. Left gastric angiography showed a moderate number of tumor vessels through out the lesion in the fundus. The serum ferritin level revealed 307 ng/ml, which is very high. When the abdominal cavity was opened cystic lesion measuring approximately 25 cm in diameter was seen to protrude from the submucosal tumor in the fundus. The pathological diagnosis was leiomyosarcoma of the stomach with giant cyst formation. The ferritin level of the fluid in the cyst was 22800 ng/ml.
