Acute renal failure in typical Kawasaki disease

Few cases of Kawasaki disease with acute renal failure have been described and only three articles report histological findings. We present an 8-year-old boy with typical Kawasaki disease and acute renal failure who did not require dialysis and had a complete recovery. Pathological findings in percutaneous biopsy included tubulointerstitial nephropathy with mild mesangial expansion, without vessel involvement or deposits in basal membrane. These findings were similar to those previously reported. We also detected apoptotic bodies in tubules. Received: 11 June 2001 / Revised: 2 January 2002 / Accepted: 4 January 2002
