History of the present illness

This is a 30-year-old female who self-referred for wisdom tooth removal. The oral surgeon noted a swelling in the right posterior maxilla of unknown duration which was confirmed by a panoramic radiograph. The radiograph shows a well-demarcated mixed radiolucent/radiopaque lesion between teeth #s 3 and 4 (Figure 1). It is buccally and palatally expansile, pushing superiorly into the right maxillary sinus. It is displacing teeth #s 3 and 4 apart and is described to be 2 x 2 x 1.7 cm in size. It is otherwise asymptomatic and the involved teeth are vital.
