A chondroma is a benign cartilaginous tumor, which is encapsulated with a lobular growing pattern.

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

Presentation[]

Characteristic features of this tumor include the vascular axes within the tumor, which make the distinction with normal hyaline cartilage.^{[citation needed]}

Diagnosis[]

Classification[]

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)

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]
