Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. [1] A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. About 30% of bone sarcomas are chondrosarcomas. [2] It is resistant to chemotherapy and radiotherapy. Unlike other primary ...
Mesenchymal Mesenchymal chondrosarcomas can grow quickly but unlike other types may respond to radiotherapy, and chemotherapy. [8] They have densely packed small round blue cells like those in Ewing's sarcoma. [9] Type II collagen can help distinguish it from other tumours. [10]
A sarcoma is a malignant tumor, a type of cancer that arises from cells of mesenchymal (connective tissue) origin. [1] [2] Connective tissue is a broad term that includes bone, cartilage, muscle, fat, vascular, or other structural tissues, and sarcomas can arise in any of these types of tissues.

EMC was firstly described in 1953 by Stout et al. when they discussed the different species of extraskeletal chondrosarcoma, [2] but EMC concept was firstly proposed in 1972 by Enzinger et al. [3] Brody thought that this was a unique low-grade malignancy with a low growth rate and both clinically and histopathologically distinct anamnesis beside the typical chondrosarcomas. [4]
Sarcoma: Cancers arising from connective tissue (i.e. bone, cartilage, fat, nerve), each of which develop from cells originating in mesenchymal cells outside of the bone marrow. Lymphoma and leukemia : These two classes of cancer arise from immature cells that originate in the bone marrow, and are intended to fully differentiate and mature into ...
There is a variety of chemotherapy treatment protocols for bone tumors. The protocol with the best-reported survival in children and adults is an intra-arterial protocol where tumor response is tracked by serial arteriogram. When tumor response has reached >90% necrosis surgical intervention is planned. [16] [17]
