Chondrosarcomas are more likely to occur in the vertebral area than osteosarcoma. Approximately 10% of all chondrosarcomas are localized on the vertebrae. In the spine, they arise mostly from the thoracic vertebrae, whereas their involvement with sacral bone is seen only rarely. Chondrosarcoma is usually seen in patients aged between 40 and 50 years. There are primary and secondary forms (after osteochondroma malignant degeneration). Histologically, chondrosarcomas are graded according to the contents of lobules of hyaline cartilage separated by fibrovascular bands. The high grade of the tumor, its nearness to vital organs, and risk of axial instability may produce serious surgical results. In this study, a 38-year-old patient diagnosed with chondrosarcoma, grade 3, is evaluated. © 2011 Lippincott Williams & Wilkins, Inc.
