Is osteochondroma benign or malignant?

Should I worry about osteochondroma?

If the osteochondroma is causing pain or loss of motion, your doctor may recommend surgery. A normal osteochondroma will not grow after your child stops growing. Children need to be taught that if their bumps get bigger once they become adults or if they start having pain, they need to see a doctor.

What is the percentage of malignant transformation of osteochondroma?

Malignant transformation is seen in 1% of solitary osteochondromas and in 3%–5% of patients with HME. Continued lesion growth and a hyaline cartilage cap greater than 1.5 cm in thickness, after skeletal maturity, suggest malignant transformation.

Is surgery needed for osteochondroma?

Most of the time, an osteochondroma does not require surgery. If the tumor causes pain, it can be removed by surgery.

How long does osteochondroma surgery take?

The operation is straight forward taking between 30 minutes to an hour to do. General risks include: infection. wound splitting and a widened scar.

How do you treat osteochondroma?

In cases where surgery is necessary, the treatment of choice is complete removal of the tumor. This involves opening the skin over the tumor, locating the osteochondroma, and cutting it off of the normal bone. Depending on the location of the osteochondroma, surgical removal of the lesion is usually successful.

How often do osteochondromas become cancerous?

Osteochondromas are typically benign; however, in some instances these tumors become malignant (cancerous). Researchers estimate that people with hereditary multiple osteochondromas have a 1 in 20 to 1 in 200 lifetime risk of developing cancerous osteochondromas (called sarcomas).

Is osteochondroma genetic disorder?

Hereditary multiple osteochondromas (HMO) is a rare genetic disorder characterized by multiple benign (noncancerous) bone tumors that are covered by cartilage (osteochondromas), often on the growing end (metaphysis) of the long bones of the legs, arms, and digits.

Can osteochondroma be misdiagnosed?

In the current case, no initial biopsy was performed, leading to a misdiagnosis of osteochondroma. Consequently, the patient received an inappropriate treatment while appropriate treatment was delayed. Misdiagnosis can have dire consequences and this error could have been avoided if greater care was taken.

Do Osteochondromas grow back?

It is possible that a benign growth or tumor can later become cancerous. It is also possible that a tumor that has been removed will grow back. Osteochondroma is the most common form of benign tumor growth in bones.

Who is most at risk for osteosarcoma?

Age. The risk of osteosarcoma is highest for those between the ages of 10 and 30, especially during the teenage growth spurt. This suggests there may be a link between rapid bone growth and risk of tumor formation. The risk goes down in middle age, but rises again in older adults (usually over the age of 60).

When does an osteochondroma stop growing?

Less commonly, osteochondromas will occur as multiple tumors. Although osteochondromas do not spread beyond the affected bone, they may grow in size as your child grows. An osteochondroma ordinarily stops growing when a child reaches full height (around age 14 in girls and 16 in boys).

How does osteochondroma affect the body?

Osteochondroma is an overgrowth of cartilage and bone that happens at the end of the bone near the growth plate. Most often, it affects the long bones in the leg, the pelvis, or the shoulder blade. Osteochondroma is the most common noncancerous bone growth.

What does it mean when a tumor is malignant?

The term “malignant” indicates that there is moderate to high probability that the tumor will spread beyond the site where it initially develops. These cells can spread by travel through the blood stream or by travel through lymph vessels.
