Case report of an epidermoid cyst at the floor of the mouth

SUMMARY Dermoids cysts of the oral floor are rare benign tumours, who having three histological aspects: dermoid, teratoid, and epidermoid. This one is characterized by the presence of a squamous stratified epithelium with cutaneous remnants. We report a case of an epidermoid cyst of the oral floor, on a 23 years old man, who presented a submental mass increasing volume, generating progressively difficulty of elocution and chewing. The ultrasonography completed by a CT-scan, showed a cystic mass, echogene and well limited. The treatment consisted in a surgical excision. The features of this observation are identical to those of the other cases returned in the literature. (Med Buccale
