How do you treat osteoblastoma?
Surgery is the treatment of choice for osteoblastoma. The goal of surgery is complete excision of the tumor. This is a more difficult process for osteoblastomas in the spine than in other locations, as it may not be possible to safely remove the entire tumor. However, the outcome for most patients is very good.
What is osteoblastoma and osteosarcoma?
Osteoid osteoma and osteoblastoma are benign bone-forming tumors commonly involving the axial skeleton. Osteosarcoma is a high-grade malignant neoplasm of bones in which the tumor cells produce osteoid to any extent; they occasionally originate from soft tissue (extraskeletal osteosarcoma).
Is osteoblastoma curable?
Vertebral osteoblastoma is a rare benign tumor primarily of the posterior elements. It is curable by resection and has a good prognosis.
Is osteoblastoma painful?
Patients with osteoblastoma usually present with pain of several months’ duration. In contrast to the pain associated with osteoid osteoma, the pain of osteoblastoma usually is less intense, usually not worse at night, and not relieved readily with salicylates (aspirin and related compounds).
Are 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 is the difference between osteoid osteoma and osteoblastoma?
Histologically, osteoid osteoma and osteoblastoma are similar, containing osteoblasts that produce osteoid and woven bone. Osteoblastoma, however, is larger, tends to be more aggressive, and can undergo malignant transformation, whereas osteoid osteoma is small, benign, and self-limited.
Does osteoblastoma come back?
Osteoblastoma returns in approximately 10 to 20% of patients. The likelihood of the tumor recurring is related to how well it can be completely removed without causing damage to normal structures.
What causes osteoblastoma?
The exact cause of osteoblastoma is unknown. It typically occurs in the second decade of life, but patients range in age from about 5 years to 45 years. It affects males more than females at a ratio of 3:1.
What are the symptoms of osteoblastoma?
Symptoms of osteoblastoma include:
- Sustained pain (which is less likely to respond to over-the-counter common pain relievers like Tylenol or ibuprofen)
- Swelling and tenderness.
- Pinched nerve (nerve compression) in the spine.
What does osteoblastoma mean?
Osteoblastoma is a slow-growing tumor that dissolves normal, healthy bone and makes a new type of abnormal bone material called osteoid. This osteoid bone material builds up around normal bone. Because the osteoid bone is weaker than normal bone, the area surrounding the tumor becomes more vulnerable to fracture.
What is an osteoblastoma?
Is osteoblastoma a benign tumor?
What are the symptoms and signs of bone cancer?
What is the cause of osteoma?
Types. Compact: These are made of very dense bone material.
Osteoblastoma: A noncancerous tumor in bone tissue. Osteoblastomas are small and are seen most frequently in children and young adults. Symptoms include pain and bone-mass reduction. Treatment includes surgery, sometimes followed by chemotherapy.
What are osteoblast cells?
Osteoblasts are the bone-forming cells that derive from the mesenchymal stem cells of the bone marrow, which also form chondrocytes, myocytes, and adipocytes. Osteoblasts are cuboid-shaped cells that form clusters covering the bone surface.
