title: Mandibular Osteolytic Lesion Associated with Exuberant Hyaline Ring Granuloma Reaction.
abstract: OBJECTIVE
  To report an unusual case of oral hyaline ring granuloma (HRG) that caused an extensive osteolytic lesion.
  
  
  METHODS
  A 22-year-old female was referred to our hospital with a large expansile cystic lesion in the left mandibular ramus associated with a clinically visible, partially erupted third molar. A diagnosis of paradental cyst was made. After marsupialization of the lesion, histopathological analysis of the surgical specimen showed an unusual exuberant HRG reaction supported by scarce fibrous stroma.
  
  
  CONCLUSIONS
  This was a case of exuberant HRG reaction that caused extensive bone destruction.
