Epidermoid Cyst of the Tongue—A Rare Case

Abstract

Introduction Epidermoid cysts are commonly found in various part of the body, but its occurrence in the oral cavity is relatively rare. Case presentation Present case highlights the importance of involvement of epidermoid cyst within the tongue in 10-year-old child. Discussion The occurrence of epidermoid cyst within the tongue is an extremely rare phenomenon and only few cases have been reported in the literature. Clinically they are painless, slowly growing mass causing difficulty in breathing, eating and swallowing Imaging modalities most importantly; ultrasonography helps in the evaluation of the lesion. However, histopathology remains the mainstay for definitive diagnosis in such conditions. Conclusion From the present case, it is concluded that such type of cases needs to be reported as it highlights the importance of keeping the rarities in mind along with common lesions while making a diagnosis.

“…Dermoid cyst (DC) is a rare development derived injury, arising from epithelial rests resulting from the union of the first and second gill arches, and histologically it may be classified as true dermoid cyst, epidermoid cyst (EC), and teratoma [1][2][3][4] . When it occurs on the head and neck, it corresponds to up to 7 % of the cases 1,2,[4][5][6] , and in only 1.6 % of the cases it appears in the oral cavity, and the floor of the mouth is the most affected area 1,4,5,7 .
