Is chondroblastoma benign or malignant?

Although a chondroblastoma is considered a benign tumor, it has the potential to spread (metastasize) to the lungs. Metastasis is rare, occurring in less than 1 percent of cases. The tumor can cause pain, inflammation, joint stiffness, limping, and other symptoms.

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.

Can chondroblastoma become cancerous?

Aggressiveness in chondroblastoma can be subdivided into three types; malignant chondroblastoma, benign chondroblastoma with lung metastasis and benign chondroblastoma with subsequent development of high-grade malignancy. Subsequent development of malignancy is common in post-irradiation cases.

Is chondroblastoma serious?

No. Chondroblastomas are benign, meaning that it’s a non-cancerous tumor. Removing the tumor with surgery alleviates pain as well as any bone damage.

What do you mean by chondroblastoma?

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.

How does chondroblastoma happen?

What causes chondroblastoma? The exact cause of chondroblastoma is not known. The tumors are believed to start from immature cartilage producing cells called chondroblasts.

What are the symptoms of chondroblastoma?

What are the symptoms of chondroblastoma?

  • Pain in the knee, hip, and shoulder joint (pain may be slight or moderate and may be present for months or years)
  • Withered or shrunken appearance of the muscle near the affected bone.
  • Impaired mobility of the adjacent joint.
  • Fluid buildup in the joint next to the affected bone.

Is chondroblastoma common?

Chondroblastoma is a rare type of noncancerous bone tumor that starts from cartilage. It most often affects the ends of the long bones, near the growth plate, in the arms at the shoulder, and in the legs at the hip and knee. It is more common in children and young adults affecting males more than females.

What is a chondroblastoma?

Do benign bone tumors need to be removed?

Most benign tumors respond well to surgical removal. In many cases, the likelihood that the tumor will come back is low — usually less than 5%. Some benign bone tumors, like giant cell tumors of bone, have a higher rate of return, but there are good methods to treat these tumors if they do come back.
