Dermoid Cysts of the Floor of the Mouth in the Pediatric Patient: Report of 2 Cases

Joshua M Abrahams, Shawn A McClure


Dermoid cysts of the floor of mouth are rare in the pediatric population and account for only 0.01% of all oral lesions. They arise as a result of failure of the surface ectoderm to separate from the underlying structures. In the pediatric patient, the initial differential diagnosis is often challenging due to multiple similar appearing lesions, which can occur in the floor of mouth. We report two cases of dermoid cysts in the floor of mouth, and briefly discuss the etiology, differential diagnosis, and treatment in the pediatric patient.
