Sternum bone giant cell tumor resection and chest wall reconstruction after the excision of breast cancer.

Giant cell tumor (GCT) is generally treated with wide surgical excision, but the local bone tissue dysfunction is a major complication. Here, we report a sternum GCT patient who had previously undergone a mastectomy. The tumor was excised, and the patient accepted chest wall reconstruction. The patient recovered well and suffered no recurrence at the first year follow-up.
