Epidermoid Cyst in the Floor of Mouth with Sub Mental Component

Abstract

Epidermoid cysts in the oral cavity are very rare. They are slow and progressive in growth. Although congenital, they are diagnosed in second or third decayed of life. Epidermoid cyst in the floor of mouth is painless, doughy in consistency, fluctuant lesion and causes no symptoms until they are large enough to interfere with chewing or speech. In this article a 23 years old girl presented with lesion almost filling the oral cavity as well as sub mental component giving appearance of double chin. Lesion was surgically enucleated intraorally. Histopathological examination confirmed the presence of epidermoid cyst. Patient did well post operatively and there was no evidence of recurrence upto 1 year of follow up.

Dermoid and epidermoid cysts of the oral cavity: a 48-year retrospective study with focus on clinical and morphological features and review of main topics

“…However, these cysts can also be found on the tongue, lips and other oral mucosa locations (3,4). ECs are the most common, and several mechanisms have been proposed for their formation, such as the proliferation of ectodermal remnants during embryogenesis, obstruction of pilosebaceous units or traumatic implantation of epithelial cells (5,6). In relation to DCs, these appear to be derived from epithelial remnants included during the union of the midline of the first and second gill arches (3,4,7).…”

“…In addition, dysonogenic, traumatic and thyroglossus anomaly theories have been postulated as being responsible for their pathogenesis (3,4,7). Despite their congenital origin, these cysts are often diagnosed in the second and third decades of life (3,7), clinically presenting as painless swellings which, in some cases, may interfere with phonation, chewing or swallowing (6,7). ECs are always coated by keratinized stratified squamous epithelium without dermal appendages within the underlying fibrous connective tissue.…”

“…ECs are always coated by keratinized stratified squamous epithelium without dermal appendages within the underlying fibrous connective tissue. DCs present, in addition to ECs characteristics, dermal appendages such as hair follicles, hairs and sebaceous and sweat glands (3,4,6,7). DCs and ECs can be present in approximately 60% of cases of hereditary familial polyposis and Gardner's syndrome.…”

Quiste Epidermoide Gigante en Reloj de Arena del Piso de la Cavidad Oral

“…Cuando el crecimiento es por sobre este músculo, produce glosoptosis resultando potencialmente en disfagia, disfonía y disnea. Cuando el crecimiento es por debajo del músculo, se presenta como un aumento de volumen submental (Neville et al, 2009;Chaudhry et al, 2013;Mesolella et al, 2013;Gaddikeri et al, 2014& Tandon & Gupta, 2014.…”
