What is an enchondroma?
A person with an enchondroma has a benign tumor, caused by an overgrowth of cartilage cells that line the joints. Enchondromas are most common in those who are 10 to 20 years old. Benign tumors are abnormal growths of cells that have formed a detectable mass. Benign tumors are not cancerous because they do not spread to other areas of the body. Enchondromas are most commonly located in the hands and feet. An enchondroma is the most common type of tumor affecting the hand bones.
What are the symptoms of an enchondroma?
Symptoms of enchondroma include joint pain, hand pain, foot pain, shoulder pain, and hip pain. Weakening of the bone can result in a fracture.
How does the doctor treat an enchondroma?
The treatment for enchondroma depends on a number of factors, including age, location of the tumor, and potential for fracture. Treatment may include bone grafting and surgery.
