==General==
*Rare variant of chondrosarcoma.
*2–10% of primary chondrosarcomas
*Adolescents and young adults
*Female predilection
*Most commonly intraosseous but can occur in extraskeletal sites especially the central nervous system (from the meminges)
*Conceptualized as originating from a pleuripotential mesenchymal cell with foci recapitulating enchondral ossification.
*The small cells appear to be an undifferentiated cartilage stem cell which “differentiate” into benign cartilage <ref>{{Cite journal  | last1 = Fanburg-Smith | first1 = JC. | last2 = Auerbach | first2 = A. | last3 = Marwaha | first3 = JS. | last4 = Wang | first4 = Z. | last5 = Rushing | first5 = EJ. | title = Reappraisal of mesenchymal chondrosarcoma: novel morphologic observations of the hyaline cartilage and endochondral ossification and beta-catenin, Sox9, and osteocalcin immunostaining of 22 cases. | journal = Hum Pathol | volume = 41 | issue = 5 | pages = 653-62 | month = May | year = 2010 | doi = 10.1016/j.humpath.2009.11.006 | PMID = 20138330 }}
