SymptomsSwellings in fingers[1]

A chondroma is a noncancerous cartilaginous tumor, usually in the fingers.[1][2]

It is very rare.[1]


Based upon location, a chondroma can be described as an enchondroma or ecchondroma.[citation needed]

  • enchondroma - tumor grows within the bone and expands it
  • ecchondroma - grows outward from the bone (rare)

Signs and symptoms

They can be single or multiple (Ollie's disease), and have a tendency to occur in fingers and toes where the bones are like tubes.[2][3]


Tumor cells (chondrocytes, cartilaginous cells) resemble normal cells and produce the cartilaginous matrix (amorphous, basophilic material).


A well-defined area of bone loss in the medulla of the bone is seen on x-ray.[2]


Treatment involves surgical removal of the tumor and bone grafted bone grafting.[2]
