Recurrent high-grade chondrosarcoma abutting the right ventricular outflow tract

Chondrosarcoma is the most common malignancy of the sternum. Removal of the sternum for a malignant tumor results in large defects in bone and soft tissue, causing deformity and paradoxical chest wall movement, making subsequent repair of the thorax very important. Herein we report a rare case of recurrent anterior chest wall chondrosarcoma after surgery 4 years earlier. The patient underwent resection of the chondrosarcoma followed by three-layer chest wall reconstruction with a split rib graft for the bony defect. He had an uneventful postoperative course and was healthy at 9 months postoperatively.
