ABSTRACT
Congenital cystic lesions of the lung are uncommon and a conjunction of two or more lesions is very rare. We report here on a case of coexisting intrapulmonary bronchogenic cyst and congenital cystic adenomatoid malformation in a 13-year-old female with a cystic mass in the right upper lobe of the lung. Computed tomography showed a cystic lesion measuring 2.5 cm with an air fluid level and surrounding multicystic lesions in the right upper lobe. On gross examination, the cut surface showed a cystic mass containing inspissated mucinous material, and the cystic mass was surrounded by multiple small cysts. Microscopically, the larger cystic cavity was lined with pseudostratified ciliated columnar epithelium. The submucosal tissue contained mucinous glands and plates of cartilage. The surrounding smaller cysts or irregular spaces were lined with bronchiolar-type respiratory epithelium. We propose that this hybrid lung lesion may represent the missing link in a common embryologic pathway determined by the timing of mesenchymal and epithelial interactions.
