Two Cases of Leiomyosarcoma in Stomach / 대한소화기내시경학회지

Leiomyosarcomas make up approximately 1 to 3% of all gastric neoplasms. The most prevalent age group was 6th and 7th decades. The main symptoms and signs were abdominal pain and bleeding. They most frequently involve gastric body and often ulcerate and bleed. Diagnosis can be established only by exploratory operation and histologic examination. Leiomyosarcomas rarely invade adjacent viscera and characteristically do not metastasize to lymph nodes, but they may spread to the liver and lungs. The treatment of choice is surgical resection. We report two cases of gastric leiomyosarcoma which was successfully treated surgically.
