A congenital foregut malformation with a laryngeal bronchus.

We present the case of a 2-month-old boy who required intubation at birth for stridor, at which point a supraglottic cyst was noted. With recurrence of the cyst, a subsequent computed tomographic scan and magnetic resonance imaging demonstrated a mass encroaching on the larynx, descending into the mediastinum, and encasing the major vessels. A median sternotomy and transcervical incision enabled excision of a well-defined mass with a laryngeal attachment. This attachment was consistent with a bronchus on histopathologic investigation. To our knowledge, this is the first reported case of ectopic lung tissue arising from the larynx and descending into the mediastinum.
