[Acute renal insufficiency associated with lymphoma. A new case]

We report on a case of acute renal failure secondary to relapse of a centrocytocentroblastic non-Hodgkin's lymphoma. Twenty-seven cases of acute renal failure due to lymphomatous infiltration of the kidneys have been so far reported. The clinical presentation is non-specific; the size of the kidneys appears normal or enlarged; diagnosis is confirmed by renal biopsy and/or CT scan examination. Chemotherapy and/or radiotherapy sometimes lead to dramatic improvement of renal function. However, prognosis is poor, mostly due to lymphomatous evolution.
