The cause for osteochondromas is not known, occurs equally in both males and females, and is not from an injury. They may be associated with a particular gene, EXT1, but the link between the two is not well understood.
If you have an osteochondroma, you probably do not know you have the tumor. They are most commonly diagnosed in people between the ages of 10 and 30. Symptoms include:
- A painless bump near the joints.
- Pain with activity. An osteochondroma may be located under a tendon, and it may move and snap over the bony tumor, causing pain.
- Numbness or tingling. Osteochondromas may be located near a nerve. When the tumor puts pressure on the nerve, there may be numbness or tingling in the associated limb.
- Changes in blood flow. A tumor that presses on a blood vessel may cause periodic changes in blood flow. This can cause loss of pulse or changes in color of the limb.
The podiatrist will order x-rays and possible CT scans or a MRI. If the doctor feels that the tumor is not an osteochondroma he will take a biopsy to check for cancer.
Most solitary cases of osteochondroma are left alone, watched over time by your podiatrist. Surgery may be considered if the osteochondroma:
- Causes pain
- Puts pressure on a nerve or blood vessel.
- Has a large cap of cartilage.
