Epidermoid cyst of the tonsil: a rare finding

Abstract

Epidermoid cysts (ECs) are benign lesions that can be encountered throughout the body, but with a low incidence in the head and neck (1.6 to 7%). In oral cavity, the most common affected site is floor of the mouth, but tonsillar location remains extremely rare (less than 0.01%). Here we present an epidermoid cyst of the right palatine tonsil which was incidentally detected in a patient who consulted for a chronic headache.

Epidermoid cyst of the facial skin: an investigative case report

“…However, in cases of hard-to-reach cystic locations or swellings proving difficult to evaluate, the use of CT/MRI is encouraged. 16 – 18 …”

Cisto epidermoide em assoalho bucal: relato de caso

“…Assim como os CD e os CT, os CE estão no mesmo espectro e representam lesões císticas que se encontram preenchidas com material semelhante ao sebo e apresentam características semelhantes, como aparência nodular bem circunscrita e falta de sensibilidade (Bouatay, Jellali, Abdejelil, & Koubaa, 2019). Acentuando-se o fato de que CD e CE possuem comportamento clínico muito semelhante, após o descarte da possibilidade de ser uma Rânula, a hipótese diagnóstica presuntiva foi de CD, o que posteriormente veio a ser descartada, uma vez que o resultado da biópsia foi de CE.…”

“…Sendo desenvolvidos a partir de componentes epiteliais anormais do tecido ectodérmico formado durante o período fetal ou epitélio implantado após cirurgia ou trauma, os CE, que também são conhecidos como cistos epidérmicos, podem ser congênitos ou adquiridos. Na cavidade oral, os locais mais comuns são o assoalho da boca ou a mucosa lingual, labial ou oral (Pereira, Alves, Araújo, Pereira, & Costa, 2008;Bouatay, Jellali, Abdejelil, & Koubaa, 2019).…”

Tonsillar Actinomycosis with presence of Epidermal inclusion cyst: Report of a rare entity

“…EIC can be developed during the fetal period from abnormal epithelial components of ectodermal tissue or they may arise after trauma or surgery due to implanted epithelium. [1][2][3] EIC can occur in any part of the body, with approximately 1.6-6.9% of cases in the head and neck area. In oral cavity, the most common affected site is floor of the mouth, but tonsillar location remains extremely rare (less than 0.01%).…”

“…In oral cavity, the most common affected site is floor of the mouth, but tonsillar location remains extremely rare (less than 0.01%). 2 Treatment of EIC of the head and neck is surgical and also depends on the localization and the size of the lesion. Histopathological examination is of utmost importance in every resected tonsil to differentiate benign inclusion cysts from tonsillar squamous cell carcinomas.…”
