Chondrosarcoma, NOS
Prostate gland


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.
