A chondroma is a noncancerous cartilaginous tumor, usually in the fingers.
It is very rare.
Based upon location, a chondroma can be described as an enchondroma or ecchondroma.
- 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.
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.
X-Ray right middle finger: juxta-cortical chondroma
MRI right knee: periosteal chondroma
Treatment involves surgical removal of the tumor and bone grafted bone grafting.
