title: Leiomyosarcoma of urinary bladder in children.
abstract: A case of leiomyosarcoma of the bladder is reported in a fourteen-year-old girl who is alive and without evidence of disease two years after partial cystectomy. Electron microscopy confirmed its smooth muscle nature. The data for 7 other children, including follow-up for 5, are tabulated. Partial cystectomy with adequate margin appears to be the treatment of choice when feasible. The tumor may be controlled with chemotherapy and radiation therapy in unresectable cases.
