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.

dyschondroplasia

(1) A nonspecific term for any defect in chondrogenesis that extends into the metaphysis and diaphysis. 
(2) Enchondromatosis, see there.

en·chon·dro·ma·to·sis

(en'kon-drō-mă-tō'sis)
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.
Synonym(s): dyschondroplasia.

dyschondroplasia

A 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.
