A sarcoma (from the Greek ÏÎ¬ÏÎ¾ sarx meaning flesh) is a cancer that arises from transformed cells of mesenchymal origin. Thus, malignant tumors made of cancellous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas.This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma.Human sarcomas are quite rare. Common malignancies, such as breast, colon, and lung cancer, are almost always carcinoma.his is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma.

Mesenchymal chondrosarcoma is an extremely rare, often aggressive form of cancer. It is a variant type of conventional chondrosarcoma. Conventional chondrosarcoma is a form of bone cancer that arises from cartilage cells. Cartilage is the specialized tissue that serves as a buffer or cushion at joints. Most of the skeleton of an embryo consists of cartilage, which is slowly converted into bone. Approximately two-thirds of cases of mesenchymal chondrosarcoma affect the bones, especially the spine, ribs or jaws.
