History of the present illness

This is a 17-year-old female with expanding anterior mandible. A panoramic view of the anterior mandible shows a large and slightly well-demarcated multilocular radiolucent lesion interspersed with foci of mixed radiolucent/radiopaque component (Figures 1 & 2). This lesion is of unknown duration and the swelling is described to measure 5.0 x 1.5 x 2.0 cm at its greatest dimensions. The swelling is noted more in the buccal vestibule. It is otherwise asymptomatic and the associated teeth are vital.

Figure 1 This radiograph was taken at the patient's first clinical presentation. Note the relatively well-demarcated and mostly multilocular radiolucent lesion with foci of mixed radiolucent and radiopaque lesion in the anterior mandible crossing the midline.

Figure 2 This radiograph was taken in first clinical presentation. Note the relatively well-demarcated and mostly multilocular radiolucent lesion in the anterior mandible crossing the midline.
