Chondroma

Not to be confused with Chordoma.

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

Multiple chondromata of fingers
Specialty	Oncology

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]
