Sublingual Dermoid in an Adult Patient.

ABSTRACT

Dermoid cysts in the floor of the mouth are a relatively rare and unusual site of location anomalies presumed to be caused by entrapment of germinal epithelium along the lines of embryonic fusion. It presents as soft, non-painful, and slowly growing swelling along the lines of fusion during the closure of mandibular and hyoid branch arches. These cysts are developmental and histopathologically classified into three types epidermoid, dermoid, and teratoid. We are reporting a rare case of a 32-year-old female who presented in the outpatient department with complaints of painless swelling over the floor of the mouth for two years, suggesting a benign sublingual mass. This case report underscores the importance of clinical presentation, diagnostic workup, and surgical approach in achieving successful outcomes for sublingual mass.
