Intraneural and perineural epithelial structures.

The fact that numerous embryologic epithelial remnants are a normal occurrence in the oral region is well known. That some of these epithelial remnants occur within peripheral nerves is less well known. This study presents examples of intraneural epithelial rests from 3 different anatomic sites: the soft tissues of the jaws (a juxtaoral organ of Chievitz), the posterior maxilla (an ondotogenic rest), and the anterior maxilla (a nasopalatine duct remnant). The purpose of this paper is to draw the attention of surgical pathologists to this phenomenon in the head and neck in order to avoid extensive unnecessary surgery.
