Acute renal failure in lymphoma of the kidney

Involvement of kidney by lymphomatous process occurs in 30-40% of cases of lymphoma, if the disease is left untreated. Incidence of renal involvement at initial presentation is 2.7%-6%. Mostly it is in the form of insidious renal failure. Acute renal failure as initial manifestation of the disease is very rare. A case of lymphomatous involvement of the kidney, with initial presenting manifestation of ARF is discussed, and the mechanisms responsible for rarity of this is analysed.
