A chondrosarcoma is a malignancy of cartilage cells.
It is a less common primary tumour of bone than osteosarcoma and accounts for about 10% of primary bone malignancies.
Chondrosarcoma affects males twice as often as females with a peak incidence between the ages of 30 and 40 years.
It occurs most often in the pelvis, ribs, shoulder girdle and humerus.
The most common presenting complaint is of bone pain. There may be localised swelling at the site of the chondrosarcoma.
Like osteosarcomas, chondrosarcomas metastasise via the blood to the lungs at a late stage
