A Rare Case of Ectopic Colonic Mucosa Presenting With Airway Compromise in a Neonate.

ABSTRACT

This case report documents a rare and unique presentation of an oropharyngeal duplication cyst and subsequent neonatal airway management. A one-day-old premature female presented with postpartum respiratory distress requiring emergent intubation secondary to an oropharyngeal mass of the left tongue. After being stabilized and transferred to an academic center, imaging revealed a cystic lesion that was then marsupialized and drained by the otolaryngology team. Pathology demonstrated mature colonic tissue and was consistent with an enteric duplication cyst. This report highlights the importance of prenatal diagnosis and the potential of a lifesaving ex utero intrapartum treatment (EXIT) procedure.
