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.
A tumor (abnormal growth of tissue) that arises from the soft tissue. The most common types are lipomatous (fatty), vascular, smooth muscle, fibrous, and fibrohistiocytic neoplasms.
