title: Peripheral nonulcerative keratitis as a presenting sign of microscopic polyangiitis.
abstract: OBJECTIVE
  To report a 16-year-old woman who had peripheral keratitis as a presenting sign of microscopic polyangiitis (MPA), which rapidly progressed to acute renal failure.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  The patient's vasculitis was diagnosed by renal biopsy, which was evaluated with histologic, immunofluorescence, and electron microscopy. The diagnosis was confirmed by laboratory study, which showed a positive antimyeloperoxidase antibody.
  
  
  CONCLUSIONS
  MPA may rarely present with ocular findings and should be considered in the differential diagnosis when a patient has peripheral keratitis.
