Description:
A rare, slow-growing tumor that is made up of cartilage and forms on or in bones or soft tissue. It is not cancer. The tumor usually occurs in the hands or feet, but it may also occur in the upper arm, thigh, collarbone, ribs, pelvis, spine, skull, and nasal sinuses. Most chondromas do not cause symptoms, but pain, swelling, and broken bones can occur. Chondromas usually don’t spread to other parts of the body, but in rare cases they may become malignant (cancer). They can occur in both adults and children.
