Objective:
To report an unusual case of oral hyaline ring granuloma (HRG) that caused an extensive osteolytic lesion.
Clinical Presentation And Intervention:
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.
Conclusion:
This was a case of exuberant HRG reaction that caused extensive bone destruction.
