Overview
The bony lumps are usually not cancerous and grow during childhood. They can cause pain, deformity and problems with joints.
Symptoms
- Hard lumps near the joints, such as the knees, shoulders or wrists
- Pain or pressure on nerves and vessels
- Limb deformities or uneven limb length
- Reduced joint movement
- Short stature
Causes and risk factors
It is caused by changes in the EXT1 or EXT2 genes and often runs in families.
Diagnosis
Diagnosis is based on examination and X-rays. MRI may be used to look at lumps that change.
Treatment
Many lumps are monitored. Surgery may remove painful lumps or correct deformities. Rarely, a lump can become cancerous, so new pain or growth in adults should be checked.
When to see a doctor
See a doctor for new bony lumps, pain, or a lump that grows after growth has finished.
