title: Recurrence of juxtacortical chondrosarcoma arising on the rib.
abstract: Juxtacortical chondrosarcoma developing on the surface of a bone is quite rare. We report a case of juxtacortical chondrosarcoma arising on the fourth rib of a 76-year-old man. Intraregional tumor resection was performed, but local recurrence was detected after 6 months. The patient underwent wide resection including the ribs, and reconstruction of the thoracic wall. He was released with a good prognosis after a year. This case emphasizes the importance of biopsy analysis before surgery to carefully evaluate tumor spread in the cartilage and performing wide resection even if the tumor is easily separated from the bone.
