Enchondroma is a non-cancerous tumor that begins in the cartilage, which is the spongy, protective material around the joints that cushions them. It occurs most often in the joints of the hands and feet and is one of the most common types of bone tumors. Although this is not a cancerous condition, it can cause problems, such as weakness in the bones that can lead to fracture.


Experts believe enchondromas develop as a result of abnormal growth of cartilage from the growth plate at the end of bones.



Common signs and symptoms of enchondromas are:

  • Tumor becomes large enough to be visible, especially if on the hand or foot

  • Bone weakness

  • Abnormal growth in the affected area



To determine if your child has enchondroma, your specialized doctor may perform the following tests:

  • Imaging tests such as X-rays, MRIs, CT scan or bone scan

  • Biopsy



Non-Surgical Treatment

Many enchondromas do not need treatment. However, a doctor will continue to monitor them and take X-rays to make sure problems don’t develop.

Surgical Treatment

Your doctor will likely recommend surgery if your child is experiencing pain from the enchondroma or has experienced a fracture from the tumor and may also recommend surgery if there are multiple tumors or an abnormal growth is present.
