Traumatic bone cyst of the mandible in a 10-year-old boy.

Although rare, the presentation of mandibular cysts in children can be difficult for medical providers to recognize. We present a case of a 10-year-old boy who presented to our pediatric emergency department with a painful swelling of his chin on multiple occasions before the diagnosis of a traumatic mandibular bone cyst with superinfection was made. A review of the literature regarding the presentation and management of cystic lesions of the mandible in children is presented.
