title: Gastric leiomyosarcoma in a child.
abstract: Gastric leiomyosarcoma is a rare tumor in pediatric patients. The histological differentiation between leiomyoma and leiomyosarcoma is difficult. Computed tomography may allow the presumptive diagnosis of leiomyosarcoma to be made preoperatively and the surgical treatment can be planned in advance. We report a case of gastric leiomyosarcoma in a 2-year old boy. Ultrasonography and computed tomography demonstrated an inhomogeneous mass with areas of tumor necrosis and calcifications in the left upper quadrant.
