Pediatric teratomas of the head and neck are exceedingly rare. To our knowledge, noncongenital, mature cases involving the mandible have not yet been described. We present a case of an enlarging jaw mass in a young girl that was determined to be a mature teratoma with histologic characteristics resembling those of the intestine, airway, and liver.
A young African American girl presented with a 2-month history of left cheek swelling and pain. Physical examination findings were significant for a firm left-sided mandibular mass and associated displacement of dentition without evidence of regional lymphadenopathy. Computed tomographic scan revealed a destructive-appearing, multiloculated, radiolucent lesion of the left mandible measuring 6.0 × 4.1 × 4.0 cm extending from the sigmoid notch to the parasymphyseal region (Figure 1).
