title: Rapidly progressive glomerulonephritis in a boy with hypocomplementaemic urticarial vasculitis.
abstract: The present paper reports the fourth case of hypocomplementaemic urticarial vasculitis in a child. We describe a boy who, after many years of arthritis, urticaria, eye inflammation and hypocomplementaemia, developed rapidly progressive glomerulonephritis which was completely reversed by immunosuppressive therapy.
  
  
  CONCLUSIONS
  Only three paediatric patients with hypocomplementaemic urticarial vasculitis have been described. Severe renal involvement was reversible with early appropriate treatment.
