title: [Synchronous multiple renal carcinoma. Review of the literature and report of a new case].
abstract: OBJECTIVE
  Herein we describe an additional case of bilateral multiple renal cell carcinoma, a rare condition outside the context of phacomatosis.
  
  
  RESULTS
  A 57-year-old man presented with asymptomatic hematuria. He had no other remarkable medical or urological history. Radiological evaluation disclosed multiple tumors in both kidneys that required bilateral nephrectomy.
  
  
  CONCLUSIONS
  Multiple syncronous renal cell carcinoma has been described in Von Hippel Lindau disease or the polycystic conditions of chronic renal failure. A few cases have been reported in patients who did not have the foregoing conditions or were asymptomatic as the case described herein, who required bilateral nephrectomy.
