Hairy polyp of the oropharynx: case report and literature review.J Pediatr Surg. 1996 May;31(5):704-6.
Hairy polyp of the oronasopharynx is an uncommon developmental malformation that is most frequently seen as a pedunculated tumor in the neonate. Derived from the ectoderm and mesoderm, this benign tumor generally has been classified as dermoid. The clinical presentation is dependent on the polyp's size and location. A full-term girl was evaluated for an oral mass that was first noted at the time of birth. Evaluation showed a 5- x 2.5-cm soft, nontender, skin-covered mass that protruded from the oral cavity. During surgery, it was noted that the stalk was attached to the superior pole of the left tonsil. The histology of the mass was consistent with a hairy polyp. Knowledge of this type of malformation facilitates early intervention and avoids significant morbidity.
