Overview
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.
Chondromas are most common among adolescence when the bones are growing rapidly.They usually grow at a slow rate so take along time to become symptomatic.Chondromas does not infiltrate adjacent tissues.
Classification
Chondromas are classified according to their location.Endochondromas are within the bone.Periosteal chondomas are on the surface of the bone and other chondromas form in soft tissues.
