Abstract:Dermoid cysts of the floor of the mouth and submandibular area represent an unusual clinical entity. We present three such cases and review their clinical presentation and pathologic classification. This study stresses the importance of recognizing and excising any tract leading from such cysts to the midline mandible or hyoid, in order to avoid a recurrence, since these tracts may be epithelialized.
“…Dermoid, epidermoid and teratoid cysts can develop in midline or sublingual region in oral cavity [9,10]. Congenital epidermoid cysts are usually originated from fuse site of embryogenic parts especially 1 st and 2 nd branchial archs [10].…”
A 24-year-old patient was referred to our clinic for treatment of impacted wisdom teeth. The patient had odontogenic pain on upper and lower right jaw. Clinical examination showed that upper and lower right first molars have deep caries and pulpitis pain. The wisdom teeth were not seen in mouth clinically. The patient anamnesis gives no wisdom teeth extraction story in past. The orthopantomograph was taken to see the positions and situations of all wisdom teeth. Bilaterally impacted teeth surrounded by large radiolucency were detected by orthopantomograph [Table/ Fig-1].
aBstRaCtEpidermoid and dermoid cysts of the jaws are seen rarely. The formation theories of the intraosseous epidermoid cyst (IEC) are not clear. The radiographic appearance is similar with unilocular cysts. Surgical enucleation is the suggested treatment method for epidermoid cysts. This case report presents bilateral mandibular intraosseous epidermoid cysts with impacted wisdom teeth which is the first documented case in the literature.

“…Usually intra oral incision is placed for small cysts but large ones require an external approach. Post operative complications are rare and are reduced by closely following the capsule and its complete removal [8].…”
In this article we present the case of an epidermoid cyst of sublingual space along with submental extension in a 35 year old lady who presented with a mass in the oral cavity. On examination a mass was seen on the floor of the mouth displacing the tongue superiorly. Diffuse fullness was noted in the submental region. The lesion was excised under general anaesthesia with nasotracheal intubation. The entire mass was removed intra orally. The histological features were suggestive of epidermoid cyst. The patient did well postoperatively and no recurrence was seen during 8 months follow up.
“…Lateral dermoids present in the submandibular triangle between the mylohyoid muscle (laterally) and the hyoglossus and genioglossus muscle (medially). A number of authors have reported lateral dermoid cysts [2,5,7]. Lateral dermoids are believed to arise from the ventral end of the first pharyngeal pouch or from the extreme ventral end of the first branchial cleft [6].…”

“…Small cysts are palpated intraorally in the sublingual region. Large cysts are evident both in the sublingual and submental spaces, often dumbbell-shaped due to a constriction of the posterior edge of the mylohyoid muscle [7]. Lateral cysts without intraoral swelling have been described [9].…”
Dermoid cysts of the floor of the mouth and submandibular space represent an unusual clinical entity. A case of an enlarged dermoid cyst in the left submandibular space in a 19-year-old female is reported, along with a review of the literature.
