Sublingual dermoid cyst: Case report and a review of the clinical, radiological and histological aspects of this rare condition

Abstract

Dermoid cyst of the floor of the mouth is a rare condition. It usually present as a non‐tender, slow growing swelling at the sublingual region. The clinical presentation may be similar to several other conditions. We report a case of an adolescent female who present at our institution with a sublingual swelling which was initially diagnosed as a plunging ranula. The lesion was excised together with the sublingual gland and then diagnosed histologically as a dermoid cyst. Post‐operative healing was uneventful. This report will also review the current literature on the clinical, radiological and histological aspect of the dermoid cyst to give the reader a greater understanding of this rare condition.

Large Dermoid Cyst of the Floor of the Mouth - An Emphasis on Differential Diagnosis

“…Several pathologic conditions can cause masses in the floor of the mouth. Cases of dermoid cysts preoperatively diagnosed ranulae are present in literature 1,2,[4][5][6] . This may be due to their similar clinical presentation, as both are painless, soft and compressible lesions, which can cause tongue fullness, with subsequent difficulty with swallowing, speech and breathing 1,7 .…”

Validity of Intraoral surgical approach for enucleation of large plunging sublingual dermoid cysts

“…The differential diagnosis of sublingual lesions included infections, ranula, salivary gland tumor, lymphatic malformation as cystic hygroma, heterotopic gastrointestinal cyst and duplication foregut cyst. For this reason, clinical examination and conventional radiography are not sufficient for diagnosis [11,12] .…”

“…Su constitución corresponde a una cápsula fibrosa, con revestimiento de epitelio escamoso y contenido tipo detritus propio de color amarillento. Posee la capacidad de aumentar de volumen durante años de forma muy lenta y lineal, siendo las capas superficiales de la dermis su ubicación más común (Bartlett et al, 1993;Neville et al, 2009) sintomatología inicial entre los 10 y 35 años, no reportándose predilección por algún sexo (Boko et al, 2014;Kyriakidove et al, 2015;Lee et al, 2017).…”
