Osteoblastoma and giant cell tumor of bone are usually easy to distinguish.
Following are important features to be cognizant of: (1) virtually any bone can be affected; (2) it commonly involves the spine, where it has a strong propensity to involve the dorsal vertebral elements as opposed to the body; (3) it can sometimes show locally aggressive growth, which correlates mostly with surgical resectability and possibly with specific histologic features such as prominent epithelioid cell morphology ("aggressive osteoblastoma"); (4) other benign tumors such as osteoid osteoma, aneurysmal bone cyst, giant cell tumor of bone, and sino-orbital osteoma can mimic it histologically; and (5) distinguishing it from osteoblastoma-like osteosarcoma, on the basis of careful evaluation of sometimes subtle cytoarchitectural features, is essential to avoid a misdiagnosis.
