Gastric leiomyosarcoma account for about 0.5-2% of primary gastric malignant neoplasms. The most common signs and symptoms are abdominal pain, gastrointestinal bleeding, and abdominal mass. Cases of intraperitoneal hemorrhage are rare. The patient was a 25-year-old man with epigastric pain. He was admitted to our hospital with a diagnosis of acute generalized peritonitis. We detected an 8 cm gastric leiomyosarcoma with intraperitoneal hemorrhage by gastrofiberscopy, endoscopic ultrasonography, and abdominal CT examinations. At operation, massive bleeding of about 600 ml was found in the abdomen with a hematomous tumor 2.3×2.0cm in diameter growing from the antrum of the stomach. Histopathological diagnosis revealed a small low grade malignant leiomyosarcoma of the stomach. Postoperatively, he has remained healthy for 54 months.
