en·chon·dro·ma·to·sis(en-kon'drō-ma-tō'sis), [MIM*166000 *225795]
A rare disorder characterized by hamartomatous proliferation of cartilage in the metaphyses of several bones, most commonly of the hands and feet, causing distorted growth in length and pathologic fractures; chondrosarcoma may develop. When enchondromatosis is associated with hemangiomas in the cutaneous or visceral regions, the condition is called Maffucci syndrome. Most cases are sporadic but a few instances demonstrate autosomal dominant inheritance with reduced penetrance.
2. formerly, a general term encompassing both enchondromatosis and exostosis, which has caused their synonyms to become tangled.
dyschondroplasia(1) A nonspecific term for any defect in chondrogenesis that extends into the metaphysis and diaphysis.
(2) Enchondromatosis, see there.
A rare familial, and probably hamartomatous, proliferation of cartilage in the metaphyses of several bones, most commonly of the hands and feet, causing distorted growth in length or pathologic fractures; chondrosarcoma frequently develops. When combined with hemangiomas in the cutaneous or visceral regions, it is called Maffucci syndrome.
dyschondroplasiaA rare progressive disease of the growing parts of bone (epiphyses), affecting children and causing growth retardation. The bones of the limbs are abnormally short, often unequal, and show nodular swellings.
a mass of hypertrophic cartilage develops in the proximal end of the tibiotarsal bone in young broilers and turkeys. May cause lameness and limb deformity.
