Objective:
Dermoid and epidermoid cysts are rare cysts of the head and neck region, which should be considered in differential diagnosis of sublingual mass, constituting 0.01 % of all oral cavity cysts. There are suspected theories regarding the basis of the pathology.
Case Report:
30-year-old male referred to our clinic with a chief complaint of sublingual mass which had been present for many years but the lesion enlarged over the past 3 years. MRI examination revealed a giant cystic mass which was 3.6 × 3.9 mm in diameter and medially located at sublingual region.
Treatment And Prognosis:
Intraoral approach was preferred for surgery and no recurrence or complaints were detected during follow-up period.
Conclusion:
When a cystic mass is detected on the floor of oral cavity, we must consider dermoid cysts for differential diagnosis. Surgery is the only treatment. If possible, intraoral approach should be preferred because of its perfect cosmetic results.
