A very rare benign tumor composed of cartilage that grows from the surface of the bone. Cartilage is made of a tough, flexible, connective tissue found in many areas of the body and lines joint surfaces. The periosteal chondroma forms in the periosteum, a fibrous membrane made up of blood vessels and connective tissue that covers the bone. Also known as juxtacortical chondroma.

A small and noncancerous bone tumor where the cells in the tumor, called osteoblasts, make new bone. There is no risk of the disease spreading.

The most common benign tumor, which constitutes 35% of all benign bone tumors, and 10% of all bone tumors overall. It is an overgrowth of the bone that happens at the end of the bone near the growth plate. It is made up of both bone and cartilage.

A rare, noncancerous but aggressive tumor that produces bone. If left unchecked, it will continue to grow and destroy the bone. Surgical treatment is preferred. There is a high risk of recurring, or coming back, after removal.

Benign (noncancerous) and non-aggressive tumor that consists of fibrous tissue. Commonly discovered by chance during an X-Ray done for another reason, such as a sports injury. Usually there are no symptoms and it resolves by itself.

Giant Cell Tumors of Bone are benign but aggressive tumors that destroy bones and can invade soft tissues. They most commonly affect the femur, tibia, radius, sacrum and skull.

Fibrous dysplasia is not considered a tumor, but a developmental disorder of the bone. Commonly affected areas include the facial bones (craniofacial), femur, tibia, and ribs.

Eosinophilic Granuloma is a benign bone tumor that causes a disease that creates too many immune cells. They are not a cause of cancer or an abnormal mass of tissue (neoplasm). This may come from any site within any bone in the body.

Enchondromas are benign tumors that may weaken the bone. They most commonly affect the hands and feet, with the humerus and femur being common larger bones.

A Chondromyxoid Fibroma (CMF) is a slow-growing benign yet aggressive bone tumor or neoplasm. Surgery is the standard of treatment. It is important that it is removed because it can be spread to other body parts.
