Unmasking a Mimic: Recurrent Overtreated Aneurysmal Bone Cyst of the Mandible Simulating Malignant Osteosarcoma
摘要
Aneurysmal bone cysts are benign, lytic, and locally aggressive bone lesions. They predominantly affect the long bones and vertebral column (50%), but can also be found in the scapula, ribs, and spine. Involvement of the jaw bones is rare, occurring in only 2–3% of cases, with the mandible being more commonly affected. ABCs account for about 1.5% of all non-odontogenic and non-epithelial jaw cysts. Treatment options include intra-cystic injections, embolization, surgical resection, and curettage. This case report presents a significant instance of an enormous ABC in the mandible of a 28-year-old male patient, which recurred despite undergoing an aggressive segmental resection of the mandible.
