Chondrosarcoma
Pronunciation
Definition 1
A type of cancer that forms in bone cartilage. It usually starts in the pelvis (between the hip bones), the shoulder, the ribs, or at the ends of the long bones of the arms and legs. A rare type of chondrosarcoma called extraskeletal chondrosarcoma does not form in bone cartilage. Instead, it forms in the soft tissues of the upper part of the arms and legs. Chondrosarcoma can occur at any age but is more common in people older than 40 years. It is a type of bone cancer. (NCI Dictionary)
Definition 2
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. (NCI Thesaurus)
Definition 3
A malignant mesenchymal neoplasm arising from cartilage-forming tissues. (NCI Thesaurus/CDISC)
