Tumours of the central nervous system
ICD-O-3 topography code: C70, C71 and C72
ICD10: C70
           

A malignant mesenchymal tumor arising from cartilage-forming tissues involving the bones. It affects middle-aged to elderly adults, and the pelvic bones, ribs, shoulder girdle, and long bones are the most common sites of involvement. Most chondrosarcomas arise de novo, but some may develop in a preexisting benign cartilaginous lesion.

/span>hondrosarcoma (CHS) is a malignant mesenchymal tumor arising from cartilage-forming tissues, histologically characterized by a lobular growth pattern and with abundant matrix production. Myxoid changes or chondroid matrix liquefaction are common features, calcification or ossification may also be present.

> is typical.
Primary CHS is the third most common primary malignancy of bone after myeloma and osteosarcoma. It affects middle-aged to elderly adults, with a peak incidence in the fifth to seventh decades of life, with a slight preference for males. Histological parameters associated with increased risk of recurrence and metastasis include grade, tumour necrosis, mitotic count and myxoid tumour matrix
