title: Fine needle aspiration biopsy in central giant cell lesion: a report of 3 cases.
abstract: BACKGROUND
  Fine needle aspiration biopsy (FNAB) is a safe and efficient diagnostic method used in numerous lesions of the head and neck region. However, its use in central giant cell lesion (CGCL) is rarely seen.
  
  
  METHODS
  Three cases of CGCL were initially diagnosed with FNAB, emphasizing the cytologic and immunocytochemical features.
  
  
  CONCLUSIONS
  FNAB, particularly when associated with clinical, radiographic and laboratory examinations, plays an important role in the preliminary diagnosis of CGCL.
