This is a 12-year-old Hispanic girl who was referred by her general dentist for a large swelling in the left maxilla. It involved teeth #s 11-15 and the maxillary sinus (Figure 1). The lesion was of unknown duration and was 2 x 4 cm in size. The soft tissue overlying the lesion was reddish in color and the swelling was both buccal and palatal. Teeth #s 12-14 were mobile. The CT scan showed the tumor to have infiltrated the roots of the left maxillary permanent dentition. Her past medical history is unremarkable.
