title: [Synchronous renal clear-cell carcinoma and ipsilateral transitional-cell carcinoma: case report and bibliographic review].
abstract: OBJECTIVE
  We report a new case of simultaneous renal cell adenocarcinoma and ipsilateral multifocal transitional cell carcinoma.
  
  
  METHODS
  73-year-old man with initial diagnosis of transitional cell carcinoma of the urinary tract whose pathological report showed a asynchronous renal cell carcinoma.
  
  
  RESULTS
  We present microphotographs of both tumors after radical surgery.
  
  
  CONCLUSIONS
  The presentation of both tumors in the same kidney is unusual, although there are around 47 cases in the bibliography worldwide, 8 of them in Spanish. Presentation of both tumors altogether does not worsen prognosis.
