Adamantinoma | Symptoms & Causes

What are the symptoms of an adamantinoma?

While symptoms of an adamantinoma may from child-to-child, the most common include:

  • pain (sharp or dull) at the site of the tumor
  • swelling and/or redness at the site of the tumor
  • increased pain with activity or lifting
  • limping
  • decreased movement of the affected limb 

You may have noticed these symptoms over a short period of time or they may have been occurring for six months or more. In most cases of an adamantinoma, an injury brings your child into a medical facility, where an x-ray may show abnormalities in the bone. 

It’s important to keep in mind that the symptoms of an adamantinoma may resemble other medical problems, some of them which are very common and easy to treat, others which could be more serious. 

Your child may experience symptoms differently from those listed above. It is important to be evaluated by a physician to get an accurate diagnosis. Always consult your child's doctor if you have concerns.

What causes an adamantinoma?

Adamantinomas do not have an identifiable cause. If your child has an adamantinoma, he probably has sustained a trauma to the affected bone, but it’s unclear whether trauma is a cause of the tumor, or the tumor makes the bone weak and more likely to be injured.
