Epidermoid Cyst of the Floor of the Mouth

Abstract

Epidermoid cysts are rare, slow-growing, benign, developmental cysts that are derived from abnormally situated ectodermal tissue. Epidermoid cysts may grow anywhere on the body and about 7% of them are located in the head and neck region. They are usually asymptomatic over years but can be symptomatic due to secondary changes or the growing size. Clinically, the lesion presents as a slow-growing asymptomatic mass, usually located in the midline, above or below the mylohyoid muscle. Surgical excision from the floor of the mouth is indicated to relieve symptoms and prevent possible infection. This swelling on the floor of the mouth can sometimes cause serious problems with difficulty for swallowing and speaking. The purpose of this report is to present a case of sublingual epidermoid cyst of the floor of the mouth.

Unusual giant plunging sublingual epidermoid cyst: A case report and review of literature

“…We identified 40 case reports and case series on sublingual epidermoid cyst which have been summarized in Table 1 . 4 , 5 , 7 , 9 , 10 , 11 , 12 , 13 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 Patient demographics revealed a varied age range from infants to 77 years, with predominant being male. Common clinical presentations included slow‐growing, painless, non‐fluctuant swellings in the floor of the mouth.…”

Mylohyoid Muscle: Current Understanding for Clinical Management Part II: Clinical Anatomy, Radiology, and Surgical/Clinical Relevance

“…The neck can present with cystic lesions such as median and lateral cervical, epidermoid, epidermoid, and thyroglossal duct cysts. [35][36][37] An intraoral approach is recommended if the upper neck cyst is <6 cm above the mylohyoid muscle, and an extraoral approach if it is more than 6 cm below it. 38 However, some cysts located below the mylohyoid muscle have been removed by an intraoral approach using an endoscope.…”
