What are the symptoms of an enchondroma?

Most enchondromas don’t cause any symptoms. However, some children may experience pain in the affected area if any, or a combination of, the following occur:

   •   The tumor becomes very large.
   •   The tumor causes weakness of the affected bone, leading to a fracture.
   •   The tumor causes abnormal growth of the affected area.

What other conditions are associated with enchondromas?

An enchondroma may appear as a solitary tumor or as multiple tumors. In cases that involve multiple tumors, the following conditions may be diagnosed:

   •   Ollier's disease (enchondromatosis) - multiple enchondromas in various sites of the body.
               -   much less common than cases of single enchondroma.
   •   Maffucci syndrome - multiple enchondromas associated with soft-tissue hemangiomas (benign tumors made up
       of blood vessels).

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them.
