title: Polyarteritis nodosa presenting with a leg mass.
abstract: We report an unusual presentation of polyarteritis nodosa in a 2-y-old child. The child presented with a mass of the left leg adjacent to the calf, and the biopsy showed polyarteritis nodosa. Further investigations confirmed systemic features, and X-rays showed a periosteal reaction.
  
  
  CONCLUSIONS
  Childhood polyarteritis nodosa may present with a lower limb inflammatory mass.
