Abstract

Congenital cystic adenomatoid malformation (CCAM) of the lung is a rare condition with the potential for malignant transformation. Several cases that presented with malignant changes have been reported worldwide. However, no report about a malignant transformation case in a CCAM in Korea has been published. We report the first patient who had a malignant change in a CCAM. A 32-year-old female underwent a bilobectomy for a cystic lung lesion that was a type 1 CCAM associated with malignant transformation. A biopsy specimen from the resected cystic lesion showed foci of adenocarcinoma.
