The terms osteochondroma , ecchondroma and cartilaginous exostosis describe benign bone tumors . As long as the tumor is not ossified, it is called an ecchondroma or cartilaginous exostosis . The tumor after ossification is called an osteochondroma . These tumors grow stalked from the bone near the joint ( metaphysis ). They are the most common benign bone tumors. They are usually noticeable through growth in childhood. After the bone has finished growing in adulthood, the tumors usually stop growing.
Symptoms are rare and only occur when the tumor presses on other structures such as nerves or blood vessels or hinders joint movement. The tumor is usually not tender. Treatment is only necessary in the event of complaints and consists of the most complete surgical removal possible. The course and prognosis are good; malignant development is rare.
