Ollier disease is a skeletal disorder characterized by multiple enchondromas, which are noncancerous (benign) growths of cartilage that develop within the bones. These growths may lead to skeletal deformities, limb discrepancy, and fractures.
Ollier disease is a condition that affects the skeletal system, the framework for our body. This is a rare condition that occurs in approximately 1 out of every 100,000 people. Other names that Ollier disease may be called include multiple enchondromatosis or dyschondroplasia.
Ollier disease (enchondromatosis) and Maffucci syndrome are rare, classically nonfamilial conditions that are characterized by multiple intramedullary (central) cartilaginous tumors. In Maffucci syndrome, tumors also occur as soft tissue hemangiomas, which are absent in Ollier disease.
Some people with Ollier’s disease have no symptoms at all. But common symptoms include an aching pain that won’t go away or swelling or lump that makes the bone look a funny shape. Often the bone with a lot of cartilage in it grows more slowly and so sometimes one leg or arm is shorter than the other.
