Chondrosarcoma is a malignant bone tumor arising from cartilaginous tissue, most frequently occuring at the ends of the femur and tibia, the proximal end of the humerus and the pelvis; and presenting with a palpable mass and progressive pain. Chondrosarcoma is usually slow growing at low histological grades and can be well managed by intralesional curettage or en-block wide resection.

Compression of the spinal cord in the cervical region, generally manifested by paresthesias and numbness, weakness, difficulty walking, abnormalities of coordination, and neck pain or stiffness.
