Osteoblastoma
Osteoblastoma is an uncommon osteoid tissue-forming primary neoplasm of the bone.
It has clinical and histologic manifestations similar to those of osteoid osteoma; therefore, some consider the two tumors to be variants of the same disease, with osteoblastoma representing a giant osteoid osteoma. However, an aggressive type of osteoblastoma has been recognized, making the relationship less clear.
