Fig 2 (A) Low-power view shows a large predominant cyst characteristic of type 1 congenital pulmonary airway malformation with multiple surrounding smaller cysts lined by bronchiolar-type epithelium, more typical of type 2 (hematoxylin and eosin, ×20). (B) Intracystic mucinous proliferation arising in the predominant cyst (hematoxylin and eosin, ×200). (C, D) Extracystic mucinogenic proliferation composed of back-to-back glands, consistent with mucinous adenocarcinoma arising in the background of CPAM.
