Aggressive osteoblastoma of the mandible: A diagnostic dilemma.

The clinical facts and radiologic findings are very important in the diagnostic evaluation of jaw swellings, and must be considered along with histologic findings. Osteoblastoma, an uncommon primary lesion of the bone that occasionally arises in the jaws, is one such lesion causing a localized jaw swelling. Clinically, osteoblastoma can be symptomatic or even remain symptom-free, and may be diagnosed only on routine radiographic examination. Histologically and clinically, differential diagnosis for osteoblastoma ranges from a variety of benign and malignant tumors that poses a diagnostic dilemma. Stressing the importance of the correct diagnosis of such lesions, this report discusses a case of aggressive osteoblastoma of the mandible posing as a diagnostic dilemma.
