Radiolucent lesion of the anterior mandible.

CLINICAL PRESENTATION A 22-year-old white female presented with a solitary, well circumscribed, round radiolucency 15 mm in diameter, with a largely sclerotic border in the mandibular midline, seen on Panorex (Fig 1) and occlusal films. The lesion was asymptomatic and of unknown duration, and there was no detectable expansion of the jaw. The incisor teeth were nonrestored, noncarious, and vital. In addition, the patient denied previous tooth extraction or other trauma in the area. A positive history of smoking was reported. Past medical history was significant for difficulty with weight control and for a bilateral reduction mammoplasty operation. There was no history of any form of neoplastic disease.
