title: [Renal leiomyosarcoma. Apropos a case].
abstract: OBJECTIVE
  To describe an additional case of leiomyosarcoma of the kidney in a patient that presented with nonspecific abdominal pain and a palpable mass. The clinical features, diagnosis and therapeutic aspects, as well as the prognostic factors of this tumor type are reviewed.
  
  
  METHODS
  Patient evaluation included US, CT and MRI. The patient underwent a left radical nephrectomy and received adjuvant external radiotherapy.
  
  
  RESULTS
  The patient is asymptomatic and has no local recurrence or metastasis 15 months postoperatively.
  
  
  CONCLUSIONS
  Leiomyosarcoma of the kidney is an uncommon malignant mesenchymal tumor. To our knowledge, less than 100 cases have been reported in the literature. Its clinical features and the US, CT and MRI findings are not unlike those of renal adenocarcinoma. The treatment of choice is by radical nephrectomy.
