title: [Lymphomas of the urinary tract].
abstract: OBJECTIVE
  The present study discusses both primary and secondary malignant lymphoreticular proliferative tumors of the urinary tract.
  
  
  METHODS
  Two patients with urinary tract involvement are described: one female and one male with bladder and prostate involvement, respectively.
  
  
  RESULTS
  Both cases presented clinical features that were not distinct from those of other tumors of the urinary tract.
  
  
  CONCLUSIONS
  The anatomopathological study is essential to the differential diagnosis of urinary tract involvement from non-Hodgkin lymphoma and discards other extralymphatic conditions.
