Hepatorenal syndrome complicating chronic lymphocytic leukemia.

Hepatorenal syndrome and portal hypertension developed in a 59-year-old man with chronic lymphocytic leukemia. At autopsy, he had portal hypertension from lymphocytic infiltration of the liver with compression of the portal veins, and no other pathologic process in the liver. Histologic examination of the kidney did not reveal a lesion that could account for the observed renal insufficiency. This case report documents the association of a lymphoproliferative disorder with portal hypertension and hepatorenal syndrome.
