Normocomplementemic urticarial vasculitis inaugurating destructive polyarthritis.

Urticarial vasculitis is an entity characterized by recurrent bouts of urticaria and histological evidence of leukocytoclastic vasculitis. An underlying systemic disease is often present. Joint manifestations occur mainly in cases with hypocomplementemia. We report a case of destructive polyarthritis preceded by urticarial vasculitis without hypocomplementemia.
