Foregut duplication cyst of the pharynx

  • L Fraser (a1), A G Howatson (a2) and F B MacGregor (a1)

Abstract

Introduction:

Foregut duplication cysts are heterotrophic rests of foregut-derived epithelium which are usually found in the abdomen and thorax; rarely are they found in the head and neck.

Case report:

We describe the case of a pharyngeal foregut duplication cyst presenting with airway obstruction in a neonate. We also review the pathology, investigation and management of this rare condition.

Discussion:

The occurrence of a foregut duplication cyst in the head and neck region mandates vigilance with respect to the airway. Magnetic resonance imaging is a useful part of pre-operative evaluation but cannot be relied upon for definitive diagnosis. Although foregut duplication cysts are benign lesions, definitive cure ultimately requires surgical excision, and this is often the means by which a definitive diagnosis is made. The prognosis for these lesions is excellent, with no reports in the literature of recurrence following excision.
