title: Bilateral primary renal lymphoma: case report and bibliographic review.
abstract: OBJECTIVE
  To review the presentation, diagnosis and treatment of primary renal lymphoma through a new case report.
  
  
  METHODS
  We report the case of a 73-year-old man who presented at A&E with constitutional symptoms and weight loss of 9 kilograms over 3   months
  
  
  RESULTS
  Laboratory analysis showed impaired renal function, anemia and hypercalcemia. Imaging tests showed a large solid mass in the right perirenal  area with infiltration of the parenchyma and Gerota's fascia surrounding the hilum of the kidney, as well as a solid mass in the inferior pole of the  left kidney. Pathology showed the presence of lymphoid-like monomorphic cells. After establishing the diagnosis of bilateral primary renal  lymphoma  it was decided to start treatment with CHOP-Rituximab-type combination chemotherapy.
  
  
  CONCLUSIONS
  Primary renal lymphoma is a rare entity and the diagnostic technique of choice is CT. Definitive diagnosis is confirmed on histology.  In view of its aggressive nature and poor prognosis, it is important to make an early diagnosis in order to start treatment promptly. The treatment  of choice is systemic chemotherapy using a CHOP regimen.
