Fetal adenocarcinoma of the lung (FLAC) is an extremely rare subtype of lung cancer, accounting for only 0.1% to 0.5% of primary pulmonary malignancy. In 2011, international multidisciplinary classification of lung adenocarcinoma developed by the International Association for the Study of Lung Cancer (IALSC), the American Thoracic Society (ATS) and the European Respiratory Society (ERS) classified FLAC as a variant of invasive adenocarcinoma. FLAC has been further divided into low-grade fetal adenocarcinoma (L-FLAC) and high-grade fetal adenocarcinoma (H-FLAC) as these two categories exhibit different clinicopathological features and biological behaviors. Here we report a case of high-grade fetal adenocarcinoma and summarize clinicopathologic features of fetal lung adenocarcinoma.
