We report 2 cases of congenital cystic adenomatoid malformation (CCAM). Case 1. A 1-year-old boy was admitted to our hospital because he suffered from respiratory infection three times in over 4 months. Chest computed tomography (CT) showed multiple cysts in the right lower lobe, and lobectomy was performed. The cyst was histologically diagnosed as type I CCAM. Case 2. A 9-year-old girl who suffered from pulmonary abscess 2 times in 2 years was admitted to our hospital. Chest CT showed a large cyst in her right S8. Partial resection of the right S8 was performed. It was histologically diagnosed as type I CCAM with mucinous bronchioloalveolar carcinoma. Because optimal management of CCAM remains controversial, an appropriate surgical procedure should be selected.
