A cartilaginous growth or tumor.

A benign tumor of cartilage. However, many chondrosarcomas arise in preexisting chondromas.

A tumor or tumor-like growth of cartilage cells. It may remain in the interior arising from the cartilage of the medullary cavity (true chondroma, or enchondroma), or may develop on the surface of a cartilage and project under the periosteum of a bone (ecchondroma, or ecchondrosis).

MeSH	D002812

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).

Characteristic features of this tumor include the vascular axes within the tumor, which make the distinction with normal hyaline cartilage.

Based upon location, a chondroma can be described as a enchondroma or ecchondroma.^[1]
