title: Implications of thrombocytosis in giant cell arteritis.
abstract: OBJECTIVE
  To bring attention to the implications of thrombocytosis in giant cell arteritis.
  
  
  METHODS
  Case report. Platelet counts were measured before and after corticosteroid therapy in a patient with biopsy-proven giant cell arteritis.
  
  
  RESULTS
  Platelet counts were increased before corticosteroid therapy was begun and returned to normal levels after corticosteroid therapy was instituted.
  
  
  CONCLUSIONS
  Platelet counts in a patient with giant cell arteritis may have diagnostic, therapeutic, and prognostic value.
