Benign osteoblastoma of the mandible

Abstract

Osteoblastoma, a rare osteoblastic tumor, constitutes approximately 1% of all primary bone tumors. It is characterized by osteoid and bone formation with the presence of numerous osteoblasts. A 24-year-old female presented with a chief complaint of a painless swelling beneath the mandible, which was growing during the past 3 years. Radiological picture disclosed a well-circumscribed lesion with patchy radiopaque internal structure. After complete excision, the histopathological diagnosis was a benign osteoblastoma of the mandible. Differential diagnosis and immunohistochemical features are potentially useful for refining diagnosis of osteoblastoma.
