What does chondroblastoma mean?

A chondroblastoma is a rare type of noncancerous bone tumor that begins in cartilage. This is the specialized, gristly connective tissue from which most bones develop. It plays an important role in the growth process. There are many different types of cartilage in the body.

Which of the following is the characteristic feature of chondroblastoma?

Imaging characteristics Chondroblastomas usually show round or oval, geographic, lucent lesions with sharply marginated borders on radiograph,. CT scans can depict matrix mineralization, soft tissue extension, and cortical erosion.

Where are Chondroblastomas most commonly located in bone?

Most chondroblastomas are found close to the knee joint — either at the lower end of the femur (thighbone) or the upper end of the tibia (shinbone). They are also found in the shoulder at the top of the humerus (upper arm bone).

Is chondroblastoma malignant?

Chondroblastoma is currently classified as a benign neoplasm; however, chondroblastoma and chondroblastoma-like osteosarcoma have morphologic overlap, raising the possibility that some tumors diagnosed as chondroblastoma-like osteosarcoma might actually represent malignant chondroblastoma.

How do you treat chondroblastoma?

Surgery is the most common treatment for chondroblastoma and is necessary to remove the tumor, stop the pain and prevent future bone damage. If the bone is damaged, the surgeon will perform bone grafting after removing the tumor. Bone grafting replaces your damaged bone with healthy bone from another part of your body.

Is chondroblastoma life threatening?

Although usually benign, chondroblastoma metastasizes on rare occasions, with fatal results.

Is chondroblastoma serious?

Chondroblastoma is a non-cancerous tumor that causes pain, swelling and weakness in a joint. No one wants to be in pain, especially if it prevents you from living a normal life. Luckily, chondroblastomas are curable. Surgery should alleviate your discomfort and get you back to the activities that are important to you.

What is osteochondroma of the knee?

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. It most often occurs between ages 10 and 30.

How is chondroblastoma treated?

Can chondrosarcoma be cured?

Chondrosarcoma treatment often involves surgery to remove the cancer. Other treatments might be recommended in certain situations. Which options are best for you depends on where your cancer is located, how quickly it’s growing, whether it has grown to involve other structures, your overall health and your preferences.

Is osteoblastoma benign?

Osteoblastoma is a rare benign bone tumor that accounts for about 1 percent of all primary bone tumors in the United States. It affects twice as many boys as girls. Similar to most primary benign bone tumors, osteoblastoma tends to form in the extremities, however it also often forms in the spine.

What does a chondroblastoma look like on an xray?

Most chondroblastomas are small (1 to 4 cm), round tumors. On x-ray images, they are often surrounded by a thin rim of white bone. Some will cause the edge of the bone to push out, but rarely do the tumors extend past the bone and into the surrounding soft tissue.

What is the most common type of patellar tumor?

Giant cell tumor Giant cell tumor (GCT) is the most common type of the diagnosed patellar tumors (33% of all the patellar tumors) [1]. Chondroblastoma (CB) can also be found in the patella but at a very low occurrence rate (2%) [11]. It is the secondary common benign patellar tumor (16% of all the patellar tumors) [1].

What is chondroblastoma of the hip?

Chondroblastoma is a rare type of benign (noncancerous) tumor that grows at the ends of the body’s long bones, close to the joints. Most often, the tumors develop at the ends of the femur (thighbone), tibia (shinbone), or humerus (upper arm bone).

Which biopsy findings are characteristic of patellar granuloma of the patella (GCT)?

A needle biopsy or incisional biopsy of the patella is recommended for the diagnosis. The histopathological features of the patellar GCT, which mainly include numerous giant cells, short spindle-shaped cells, bone tissue calcification, and a few mitotic figures [ 2 ], should be distinguished from aneurysmal bone cyst or chondroblastoma.
