Two giant cell tumors arising from the ribs: Two case reports

Giant cell tumors of bone are a relatively common type of proliferative neoplasm. These tumors usually arise in the epiphyseal region of limbs and their occurrence in the ribs is unusual. This report describes two rare cases of giant cell tumor of the ribs. The tumors were resected with the ribs, and chest wall defects were covered with Marlex mesh. Both patients remained free of local recurrence. In one patient, however, multiple pulmonary metastases were detected on a computed tomography scan of the chest 14 months after surgery.
