Abstract

Congenital pulmonary airway malformation (CPAM) is a developmental abnormality of the lung, which results from an abnormality of branching during fetal development of the lung. We report the case of an 18 year-old woman who developed Kirsten rat sarcoma virus (KRAS) mutation positive mucinous adenocarcinoma of the lung (AC) in association with mixed CPAM type 1 and 2. This case is unique as KRAS mutation positive AC is present in a setting of both CPAM 1 and 2 in the same lesion.
