.Unusual Presentation Of Epidermoid Cyst Of The Oral Cavity -A Case Report

Aberrant ectodermal tissues during foetal period or acquired aberrant epithelial tissue due to trauma or surgery are thought to cause dermoid and epidermoid cysts. Their incidence is 7.0% in the head and neck region with submandibular, submental and sublingual spaces being the common sites. They are extremely rare in the oral cavity accounting for only 1.6 %. Majority of them occur in the floor of mouth. But other sites like buccal mucosa, tongue, softpalate, uvula may also be involved rarely.A case of a 45 year old female patient with unusual presentation of epidermoid cyst on the lateral border of tongue is presented here. This case was noteworthy due to the absence of any apparent cause explaining implantation of epithelial cells in this region.
