Abstract:
Congenital cystic adenomatoid malformation (CCAM), which is classified into five types according to size and bronchial invasion, is a rare type of developmental anomaly of the lung. CCAM is occasionally accompanied by malignancy, such as bronchioloalveolar carcinoma (BAC) or rhabdomyosarcoma. As defined by the WHO, atypical adenomatous hyperplasia (AAH) is a non-invasive spread of atypical epithelial cells in single rows along the alveolar wall, within a lesion that is usually less than 5 mm in diameter. AAH was also regarded as a pre-invasive neoplasia, especially associated with BAC and adenocarcinoma. We report a case of type II CCAM with AAH in adults, with a review of the references.
