Aneurysmal bone cyst: A radiolucent lesion of the mandible. Report of 3 cases

摘要

Aneuiysmal bone cysts (ABCs) are benign bone lesions that may arise de novo in bone1 or rarely in soft tissue.2 Typically, there is no definite pre-existing lesion (primary ABC). Areas similar to ABCs are associated with different benign conditions, including fibrous dysplasia, giant cell tumors, chondroblastoma, chondromyxoid fibroma and, rarely, malignant bone tumors, such as osteosarcoma (secondary ABCs). The recognition of any underlying process is important in understanding the clinical situation.
