Extensive epidermoid cyst of the submental region

Abstract

Epidermoid cysts are malformations that are rarely observed in the submental region. Imaging has an important role in surgical planning according to the size and location of the cyst in relation to geniohyoid and mylohyoid muscles. This article reports the case of a 15-year-old female patient complaining of submental swelling. The differential diagnosis included infection, tumor, ranula, and abnormalities during embryonic development. The lesion was surgically excised using an extra-oral approach. The histopathological examination revealed a cyst wall lined with stratified squamous epithelium with the presence of several horny scales consistent with the diagnosis of an epidermoid cyst. No recurrences were found after 1 year of follow-up.

Epidermoid Cyst of the Floor of the Mouth

“…Transcutaneous, prolonged median glossotomy, and midline incision are some of the surgical options. 9 Cysts above the geniohyoid muscle, such as the 1 in this case, are generally treated with intraoral approached excision. Excision with intraoral approach has both esthetic and functional benefits.…”

“…Excision with intraoral approach has both esthetic and functional benefits. 9 Extraoral access is required in cases located beneath geniohyoid muscle. In cases of large cysts, marsupialization has been recommended as an alternative approach.…”

“…Epidermoid cyst malignancy is not common, but it has been described. 8,9 Soft tissue tumors that were malignant were thought to be a remote possibility. Malignancy is characterized by rapid growth, lack of circumscription, fixation to neighboring tissues, and ulceration of the overlaying mucosa, all of which were not observed in the present patient.…”

Epidermoid Cysts – A Wide Spectrum of Clinical Presentation and Successful Treatment by Surgery: A Retrospective 10-Year Analysis and Literature Review

“…While small cysts may be treated by CO2- or erbium-YAG-laser [ 16 ][ 17 ][ 18 ][ 19 ], larger cysts need a surgical approach with cold steel [ 3 ][ 7 ][ 8 ]. Since skin sagging is a possible outcome after removal of larger cysts, a small sheet of the epidermis above the cyst is excised.…”

Quiste epidermoide en cavidad oral. Un reporte de caso

“…Los quistes se clasifican histológicamente como epidermoides cuando se derivan del tejido ectodérmico y se encuentran recubiertos por epitelio escamoso estratificado, dermoides cuando poseen una cavidad rodeada por epitelio similar y que contiene estructuras como glándulas sebáceas o sudoríparas; y teratomas cuando la cavidad está cubierta por epitelio que contiene algunos derivados del endodermo y mesodermo, como músculo, mucosa intestinal, mucosa respiratoria, hueso o vasos sanguíneos [1][2][3][4][5][6] . El Quiste Epidermoide (QE) es una lesión quística, benigna, poco frecuente (0,01% de los quistes de cavidad oral y 1,6% a 6,9% de cabeza y cuello) [1][2][3][4] .…”
