A rudimentary tragus in the nasopharynx: case report, literature review, and discussion of embryologic development.

ABSTRACT

We describe the rare case of a nine year-old girl with a several month history of mouth breathing and nasal obstruction due to a rudimentary tragus in the nasopharynx. We focus on the accessory tragus and its origins by describing the embryologic development of the external ear. Based on our review of the medical literature, this is the first report of a nasopharyngeal mass with a pathologic diagnosis of a rudimentary tragus.
