title: [A case of congenital cystic adenomatoid malformation of the lung in 18-year-old male].
abstract: A case of congenital cystic adenomatoid malformation (CCAM) of the lung is reported. The patient had recurrent pneumonia after the second day of delivery, and was admitted to our hospital, at the age of 18. He received right pneumonectomy under the diagnosis of CCAM. The resected lung was composed of multiple cysts with thin wall measuring 20-30 mm in diameter. Microscopic examination showed that the cyst wall was lined by ciliated columnar epithelium, and infiltration of chronic inflammatory cells was found in the submucosal layer. Bronchial cartilage was absent through the specimen. These microscopic findings are identical with those of CCAM, which is very rare in this age.
