Osteoblastoma of the jaws: current concepts and differential diagnosis.

A review of previously documented cases of osteoblastoma has been presented and an additional case has been reported. Although the clinical and histologic distinctions for fibrous-osseous lesions cover a wide spectrum, several means of differentiating osteoblastoma from similar lesions have been discussed. A larger series of cases will allow us to further delineate clinical, histologic, and biologic variables of osteoblastoma.
