Enchondroma

What is an enchondroma?

An enchondroma is a type of benign (non-cancerous) bone tumor that originates from cartilage. Cartilage is the specialized, gristly connective tissue that is present in adults and the tissue from which most bones develop. Cartilage plays an important role in the growth process. There are many different types of cartilage that are present throughout the body. An enchondroma most often affects the cartilage that lines the inside of the bones. The bones most often involved with this benign tumor are the miniature long bones of the hands and feet. It may, however, also involve other bones such as the femur (thighbone), humerus (upper arm bone), or tibia (one of the two lower leg bones).

Enchondromas are the most common type of hand tumor. While it may affect an individual at any age, it is most common between the ages of 10 and 20 years. The occurrence between males and females is equal.

What causes enchondroma?

While the exact cause of enchondroma is not known, it is believed to occur either as an overgrowth of the cartilage that lines the ends of the bones, or as a persistent growth of original, embryonic cartilage.

Treatment for enchondromas:

Specific treatment for enchondroma will be determined by your physician based on:

• your age, overall health, and medical history
• extent of the disease
• your tolerance for specific medications, procedures, or therapies
• expectations for the course of the disease
• your opinion or preference
