AB A  previously  healthy  8-year-old  boy  presented  with  2  days  of  knee  and  ankle  pain  with  no  known  cause.  His  parents  denied  that  he  had  any  trauma  or  fever.  On  physical  examination,  he  was  afebrile  in  no  apparent  distress.  His  left  knee  was  swollen  and  tender  (Figure  175-1).  He  admitted  to  other  joint  pains  but  there  was  no  swelling  or  tenderness  in  the  other  joints.  The  pediatrician  noted  a  petechial  and  purpuric  eruption  from  his  buttocks  down  to  his  ankles  (Figure  175-1).  It  was  non-blanching  but  only  barely  palpable.  There  were  prominent  circumferential  petechiae  around  the  left  sock  area.  Upon  further  questioning,  the  mother  admitted  that  her  son  had  a  viral  upper  respiratory  infection  2  weeks  ago.  A  urinalysis  showed  mild  hematuria  but  no  proteinuria.  He  never  developed  abdominal  pain.  Therapy  was  supportive  and  systemic  corticosteroids  were  not  used.
