title: Recurrent multicentric peripheral ossifying fibroma-like lesion in a child: a case report.
abstract: BACKGROUND
  Gingival hyperplasias are peculiar conditions that may produce extreme growth that impairs masticatory function and causes psychological and aesthetic disturbances. They can vary from mild interdental papillae localized growth to marked swelling affecting both jaws.
  
  
  METHODS
  The aim of this case report is to present a rare case of generalized gingival growth diagnosed in a 4 year-old Caucasian child and followed for 9 years. The lesion covered almost all of the upper and lower teeth and recurred thirty times with the same clinical and histopathological aspects. The clinical features suggested the diagnosis of idiopathic gingival fibromatosis, but the histopathological aspects did not confirm this hypothesis and were consistent with peripheral ossifying fibroma.
  
  
  CONCLUSIONS
  The present case reports a rare gingival growth with challenging diagnosis and treatment.
