Duck egg size epidermoid cyst in the floor of mouth: A rare entity

Abstract

Epidermoid cysts that appear in the midline of the head & neck are, usually, a result of entrapped ectodermal tissue of the first and second branchial arches, which fuse during the third and fourth weeks in utero. The incidence in the floor of the mouth of the oral cavity is very rare. We report a case of a large sublingual epidermoid cyst in a young male patient with emphasis on the management.
