(1,2) Several theories like primitive cartilage forming mesenchyme, chondroblastic differentiation, synovial intimal cells, past surgical or traumatic insult, inhalation of chemical carcinogens, (1) multiple hereditary exostoses, intravenous thorotrast, previous irradiation, Maffucci syndrome, and Ollier disease (4) have been postulated, but none has been considered satisfactory.

(2) Although they usually occur spontaneously, they may also arise as a result of malignant degeneration of an endochondroma, as seen in both Maffucci syndrome (a mesodermal dysplasia that causes enchondromas and hemangiomas) and Ollier disease (which manifests as multiple enchondromas).
