The vasculitides and their significance in the pediatric age group.

ABSTRACT

The vasculitides in infants and children may involve small or large cutaneous vessels and may affect a variety of internal organs. With the exception of Henoch-Schönlein purpura, vasculitis is rare in the pediatric age group. Progress has been made in determining the pathogenesis of childhood vasculitis, and there has been a significant improvement in therapy.
