Acute renal failure as first presentation of acute lymphoblastic leukaemia.

Abstract A 26-year-old man presented with acute renal failure, which appeared to be due to uric acid nephropathy occurring as a metabolic complication of acute lymphoblastic leukaemia with T-cell immunophenotype. At presentation there were neither other manifestations of leukaemic disease nor signs of a large leukaemic cell burden, which is very uncommon.
