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

Diagnosis
Classification
Based upon location, a chondroma can be described as an enchondroma or ecchondroma.Script error: No such module "Unsubst".
- enchondroma - tumor grows within the bone and expands it
- ecchondroma - grows outward from the bone (rare)
Treatment
- best left alone
- if it causes fractures (enchondroma) or is unsightly it should be removed by curettage and the defect filled with bone graft.[1]
