title: Primary leiomyosarcoma of the ureter.
abstract: We report the thirteenth case of primary leiomyosarcoma of the ureter, as well as a summary of previous cases. It is the first case reported to be studied by computer tomography and immunohistochemical procedure. Further evaluation included intravenous pyelogram, cystoscopy with retrograde pyelogram, cell block for cytology, and electron microscopy. Leiomyosarcoma is a very rare disease that is difficult to diagnose. It has a very poor 5-year disease-specific survival.
