Ollier disease

Enchondromatosis

Overview

Type of disease: Rare conditions

Ollier disease, also known as enchondromatosis, is a disorder that leads to the growth of non-cancerous tumors in cartilage. Cartilage is a type of tissue that is found inside of bones and is involved in bone growth. The most common location where Ollier disease develops is the long bones of the body, specifically in the arms and legs. Although less common, tumors can also grow in the pelvic bone, ribs, breastbone, and skull. Tumors form when a change (mutation) in DNA causes certain cells to grow out of control, resulting in the formation of a mass or a lump.

Ollier disease is present from the time of birth, and symptoms usually first appear between the ages of 1 and 10. The most common signs of Ollier disease include short limbs and bowing, or bending, of long bones which may cause difficulty walking. This disorder may cause problems with bone growth, which may result in pain and frequent fractures in the affected areas. Diagnosis may involve a physical exam, imaging studies, and other laboratory studies such as bone scans.

Treatment for Ollier disease depends on many factors such as how large the tumors are and their locations in the body. If you or a family member has been diagnosed with Ollier disease, talk to your doctor about the most current treatment options. Support groups are also available for more resources and information.
