Large congenital pulmonary airway malformation with mucinous cell clusters - a case report.

We report the clinical case of a 38 weeks gestational age neonate, antenatally diagnosed with a left large macrocystic pulmonary malformation conditioning dextrocardia. At birth, he presented with respiratory distress requiring non-invasive ventilation with high-flow nasal cannula (HFNC). A left inferior lobectomy was performed via thoracotomy on day 21 of life. Histological features of the lesion were compatible with congenital pulmonary airway malformation (CPAM) type I with muci- nous cell clusters. No surgical complications were reported and the neonate was discharged six days after surgery. Follow-up two months after surgery was unremarkable.
