Lymphoma-associated hemophagocytic syndrome: a rare cause of severe prerenal acute renal failure.

We report on a 79-year-old woman having hemophagocytosis and capillary hyperpermeability syndrome who presented with anuric prerenal acute renal failure. The patient eventually died of a hypovolemic shock. Post-mortem biopsies evidenced a highly aggressive B cell intravascular lymphoma without amyloidosis. Physicians should be aware of the risk of anuric prerenal acute renal failure in the course of lymphoma-associated hemophagocytic syndrome.
