Aneurysmal Bone Cyst (ABC) is a benign, solitary lesion of the bone first described by Jaffe and Lichtenstein in 1942. It most frequently develops in the metaphyses of long bones and vertebral bodies. ABC in the cranio-facial area presents an incidence of 3% and it occurs more frequently in the mandible than in the maxilla. Two groups of ABC have been identified based on the aetiology: primary ABC (congenital and acquired) and secondary ABC. The most common clinical feature is local swelling related to bone expansion. Pain or tenderness on palpation might be observed. At x-ray, ABC appears to be multilocular or unilocular with expansion and thinning of the surrounding cortical bone. The Authors report two cases of ABC of the jaws, observed at the Maxillofacial Surgery Department of Bellaria Hospital, Bologna (Italy) and examine the several treatment choices.
