title: [Lymphoma with initial renal involvement: four cases].
abstract: OBJECTIVE
  To present a comprehensive description of the clinical features of patients with renal manifestations during lymphoma.
  
  
  METHODS
  Retrospective review of medical records from all patients diagnosed with lymphoma associated with kidney involvement in our hospital between 1996 to 2004. Four cases were identified and analysed.
  
  
  RESULTS
  Four patients presented a non-Hodgkin's lymphoma. One patient showed intravascular large B-cell lymphoma, revealed by proteinuria. Another patient had a nephrotic syndrome, and two had a renal mass. Renal histology allowed diagnosis of lymphoma in 3 cases.
  
  
  CONCLUSIONS
  The diagnosis of lymphoma associated with renal involvement is rather difficult, and more specifically in case of intravascular large B-cell lymphoma, or even primary renal lymphoma. We present here a comprehensive review of the literature and we discuss pathogenesis of these conditions.
