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.Although similar to osteoid osteoma it is larger (between 2 and 6 cm).
