Osteosarcoma is the most common primary malignant bone tumor (5.6 per 1 million children younger than age 15 years), and Ewing’s sarcoma is second (2.1 per 1 million children). Giant cell tumor and chondrosarcoma are rare in children. Osteochondroma is more common than any of the above tumors in children, but it is not malignant.
