title: Giant cell fibroma in children: report of two cases and literature review.
abstract: BACKGROUND
  Giant cell fibroma is a type of fibrous tumour of the oral mucosa which rarely affects children under the age of 10. The purpose of this paper was to contribute two clinically and histologically documented cases of giant cell fibroma in the free gingiva of a 7 and 6 year old boys.
  
  
  METHODS
  Both nodules were presented in the mandibular anterior region. In the differential diagnosis several fibrous hyperplastic lesions were considered such as traumatic fibroma, papilloma, peripheral ossifying fibroma, peripheral odontogenic fibroma, giant cell fibroma and odontogenic hamartoma.
  
  
  RESULTS
  The lesions were removed and the histological examination revealed fibrocollagenous connective tissue with the presence of stellate giant cells which confirmed the diagnosis of giant cell fibroma.
  
  
  CONCLUSIONS
  Dentists should be aware of the existence of giant cell fibroma in children, which must be included in the differential diagnosis of nodular lesions of the gingiva and adequately diagnosed and treated by removal and histopathological examination.
