An unusual case of submental epidermoid cyst in a ten years old child: A case report

Introduction: Epidermoid cysts of the neck occur less commonly than dermoid cysts of the head and neck. They are located mostly in the submental region and present as a painless slow growing swelling. The purpose of this article is to present an unusual case of submental epidermoid cyst which showed mobility and increase in the size on deglutition which is a very unusual finding. Case Report: A 10-year-old female child reported to our centre with a complaint of painless swelling in the anterior midline of the neck. The swelling was about 5×4 cm in size. On clinical and radiological examination a provisional diagnosis of submental epidermoid cyst was made. Surgical enucleation was done under General anesthesia via an intraoral approach. Conclusion: Typically these types of cysts are not attached to the hyoid bone, but in our case it was attached both to the hyoid as well as the mandible and movement on deglutition was present which is a rare finding not reported till date. Considering the size and the location of the cyst extraoral approach was ideal for complete enucleation. But in our case we could achieve complete surgical enucleation via intraoral approach.
