Leiomysarcoma of the Stomach: Report of One Case

The incidence of the leiomyosarcoma is 1~3% of all gastric malignant tumors and 20~25% of all gastric sarcoma. It is hard to differentiate between the benign leiomyoma and leiomosarcoma 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 or other sarcoma such as lymphosarcoma. In Surgical Department, College of Medicine, Ewha Womans University, author had experienced one case of leiomyosarcoma confirmed by microscopically in 32 years old female patient, which was located in the antrum of the lesser curvature and type was endo-exogastric type. Operative procedure was made subtotal gastrectomy. I intend to report this case with review of the literatures.
