A large aneurysmal bone cyst of the clavicle in a 5-year-old child: a case report and review of literature

“…ABC is a class of bone tumor characterized by an expansile, osteolytic, and locally destructive lesion, with the presence of spongy or multiloculated blood-filled spaces of variable size that are separated by connective tissue. 2,3 It is a rare lesion that accounts for 1% of all primary bone tumors. 4 ABC usually occurs in long bones and rarely is found in short bones such as the clavicle, where these tumor and tumor-like lesions are very rare.…”

“…11 The histological appearance of the ABC is composed of reactive repair tissue with hemorrhage, therefore microscopic images of some areas of giant cell tumors, fibrous dysplasia, chondroblastoma, and osteoblastoma can resemble ABC. 2 These tumors, which are listed because of their coexistence Treatment planning should not be done without a definitive diagnosis by biopsy. 12 ABC can be classified by morphologic appearance to cystic, solid, and mixed (cysticsolid) forms.…”

“…Therefore, most of the lesions are treated by curettage and bone grafting in spite of a significant recurrence rate. 2,14 Other modalities include burr drilling, radiotherapy, cryotherapy, and vascular occlusion. We treated our patient with subperiosteal resection (without bone grafting) and closure of the periosteum.…”

“…The histological appearance of the ABC is composed of reactive repair tissue with hemorrhage, therefore microscopic images of some areas of giant cell tumors, fibrous dysplasia, chondroblastoma, and osteoblastoma can resemble ABC 2. These tumors, which are listed because of their coexistence and similarities in appearance on imaging methods, should be considered in the differential diagnosis.…”
