A 30-year-old man presented with a 1½-year history of painless swelling in the right lower jaw area that had previously been treated as an acute neck infection, without improvement. He had no recent history of dental disease or surgery. On physical examination, he was afebrile and appeared healthy. A 5 × 4-cm, nonmovable, tender mass was palpated over the right submandibular area. Dental examination revealed no active caries, but an expansile mass was observed over the right gingival area. Fine-needle aspiration of the mass disclosed yellowish mucoid fluid, and cytology only demonstrated inflammatory cells. A panoramic x-ray film was obtained (Figure 1). Computed tomography of neck was performed before (Figure 2) and 3 months after (Figure 3) surgery.
