Enchondroma of the scaphoid bone. 
The scaphoid bone is a very rare location for enchondroma.  The literature reports eight cases; five of them presented with pathologic fracture, and the youngest patient was 13 years old.  This is a report of an 11-year-old patient with scaphoid enchondroma who presented with only mild pain in the left wrist.  Magnetic resonance imaging demonstrated the lesion clearly.
