Abstract
Glandular odontogenic cysts (GOC), which account for 0.2% of all odontogenic cysts, are recognized as rare and uncommon developmental jawbone cysts with an aggressive behavior and high recurrence rate. We report a case of GOC in a man in his 50s. He presented with a painful swelling in the mandibular anterior region and a panoramic radiograph revealed a large solitary well-defined multilocular radiolucency extending from the right first molar to the left second premolar of the mandible. On histopathological examination of the biopsy tissue, the patient was diagnosed with GOC in the mandibular body, which was treated by segmental mandibulectomy and immediate reconstruction with a free vascularized fibular graft. Ten years after surgery, no findings associated with recurrence were noted.
