AB IgA  vasculitis  (Henoch-Schönlein  purpura),  the  most  common  systemic  vasculitis  in  children,  occurs  in  adults  as  well.  Typical  clinical  features  are  palpable  purpura,  arthritis,  and  hematuria.  Abdominal  pain  occurs  less  frequently  in  adults  than  in  children.  Pathologic  features  on  skin  biopsy  include  leukocytoclastic  vasculitis  with  IgA  deposition.  Biopsy  of  the  kidney  reveals  segmental  glomerulonephritis  with  crescents  and  mesangial  deposition  of  IgA.  The  cause  is  not  known.
