title: [Muscle-localized tumorlike polyarteritis nodosa].
abstract: BACKGROUND
  Systemic vasculitis presenting as a tumorlike lesion are unusual and affect mainly the uro-genital system and breast. Muscle-localized tumorlike periarteritis nodosa are scarce.
  
  
  METHODS
  We report localized tumorlike polyarteritis nodosa affecting the forearm muscles in a 90-year-old woman.
  
  
  CONCLUSIONS
  Other cases of polyarteritis nodosa localized to muscles are reviewed. This limited form has a benign clinical course and responds promptly to treatment with corticosteroids alone but relapses may occur.
