The incidence of the leiomyosarcoma is 13go of all gastric malignant tuir.´ors and 2025% of all gastric sarcoma. It is hard to differentiate between the benign leiomyoma and leiomyosarcoma by gross finding, radiologic studies and endoscopic studies, even microscopically. The main symptoms and signs are epigastric discomfort or pain, palpable mass, bleeding and anemia, weight loss and anorexia. The prognosis of the leiomyosarcoma is better than carcinoma 4r other sarcoma such as lymphosarcoma.
