Aneurysmal bone cyst of the mandible.

The aneurysmal bone cyst (ABC) is a benign, solitary lesion of bone which is most commonly found in the long bones and vertebral column. Its occurrence in the mandible is uncommon. Because of its infrequent appearance, the ABC may be mistaken for neoplastic lesions. In the past, management has consisted of curettage, cryotherapy and local resection. In this publication we present a case of ABC of the mandible. We include a review of the literature, a discussion of the etiology, pathogenesis and management of this interesting lesion.
