What is chondroblastoma?

chondroblastoma is a benign bone tumor that usually develops in children and adolescents. This type of tumor most often grows at the ends of long leg bones. It is usually limited to the ends of the bone and rarely spreads to the central part. In 10 percent of cases, the tumor develops in the bones of hands or feet. Chondroblastoma bones are very rare and include about one percent of all tumors that come from the bone. It is very unusual that this benign tumor has become cancer, but it is possible for malignancy to evolve. These cells are immature cartilage cells; When they ripen, the cells of this type are connective tissue called cartilage. Chondroblastomas are approximately twice as common in men as in women and in people aged 5 to 25 years of age are diagnosed with 90 percent of tumors. Although it is primarily a disease of younger people, this typnador has been diagnosed in individuals old as 83. There are no known risk factors, although there are several genetic mutations that are assumed to be connectedwith this type of tumor.

The most common symptom of chondroblastoma is pain. When it first occurs, this pain is mild and an injury may be attributed such as sprains or torn muscles. The pain tends to progress gradually and often there are no other symptoms. Only about 20 percent of people have noticeable swelling or lump. The absence of other symptoms often causes people to live with pain for one year or more prior to treatment.

Chondroblastoma treatment usually includes surgery to remove tumor and small amount of surrounding tissue. In order to ensure that the bone remains structurally stable, followed by the tumor removal a procedure in which the empty space that remains behind is filled with bone graft or orynthetic polymer. Most patients can restore normal activities as soon as they recover from surgery but the risk of complications such as graft failure, brokenOn the bones at the lesion site and the degeneration of the joints, it requires patients to continue to be monitored after the procedure.

chondroblastoma tumors are often repeated after removal, with a risk of recurrence between 10 and 35 percent. Tumors are more often repeated when they have more than 1.45 inches (3.7 cm) or secondary growth that spreads from a point in which the original tumor grew. The last known risk factor is the placement of the tumor. Those who have been removed from certain parts of the femur and pelvis are more likely to be abolished because of problems with the availability that make the surgeon to make sure he removed the entire tumor.
