Case report of a dermoid cyst at the floor of the mouth.

The growth of dermoid cysts at the floor of the mouth is considered a rare condition. Typically, intra-oral dermoid cysts present as non-tender, slow growing masses at the sublingual, submental and submandibular region. We report a case of a young adult male who presented at our hospital with a sublingual cyst superimposed with acute infection and failed antibiotic treatment. The cyst was excised and confirmed histopathologically as a dermoid cyst with overlying acute inflammation. Clinical progress was uneventful and postoperative recovery excellent with no recurrence.
