  A male patient with acute renal failure (ARF) due to large B-cell non-Hodgkin lymphoma infiltration of kidney is presented. The diagnosis was suspected because of coincidence of ARF and tumor lysis syndrome non-responsive to conservative renal therapies. A renal biopsy confirmed diagnosis and appropriate chemotherapy led to complete improvement of renal function.
