AB AT-A-GLANCEGranuloma  annulare  is  a  relatively  common  disorder.  The  exact  prevalence  is  unknown,  but  it  occurs  more  often  in  children  and  young  adults.A  localized  ring  of  beaded  papules  on  the  extremities  is  typical;  generalized,  subcutaneous,  perforating,  and  patch  subtypes  also  occur.The  cause  of  granuloma  annulare  is  unknown,  and  the  pathogenesis  is  poorly  understood.Pathologic  features  consist  of  granulomatous  inflammation  in  a  palisaded  or  interstitial  pattern  associated  with  varying  degrees  of  connective  tissue  degeneration  and  mucin  deposition.Most  localized  cases  resolve  spontaneously  within  2  years.
