Most enchondromas are painless tumors. Most occur in the upper arm (humerus) and thigh (femur).
Symptoms of enchondroma may include:
- Arm pain
- Thigh pain
- Joint pains:
- Bone swelling
- Bone pain:
- The development of sudden bone pain after a relatively minor injury
- Slow bone growth
- Bone tenderness:
- Back pain:
Large bone tumors can result in a progressive destruction of bone tissue. This may cause a structural weakening in the bone. When the bone becomes too weak, a fracture may occur: this is called a pathologic fracture. Sometimes a bone tumor is discovered when a fracture occurs after a minor injury.
