Mandibular aneurysmal bone cyst in an elderly patient: Case report.

OBJECTIVE: The article aims to highlight the challenge of establishing the presumptive aetiological diagnosis when unilocular or multilocular radiolucencies are identified in an elderly patient's jawbones. MATERIALS AND METHODS: A mandibular cyst-like lesion was identified in a 73-year-old patient. The therapeutic decision was cyst enucleation and grafting of the bone defect. RESULTS: The initial presumptive diagnosis was invalidated by the histopathological examination that revealed the features characteristic for the aneurysmal bone cyst. CONCLUSION: Aneurysmal bone cyst in an elderly patient is a rare condition.
