A 31-Year-Old Man with Well-differentiated Fetal Adenocarcinoma

DOI: 10.7247/jiumf.19.2.7 Well-differentiated fetal type adenocarcinomas used to be classified as subtype of pulmonary blastomas until recently. Today it is considered a rarely seen type of adenocarcinoma, characterized by low malignant potential and low mortality. In this article, we report a patient who was found to have a well-differentiated fetal type adenocarcinoma, following left lower lobectomy. We believe that the identification of this cancer subtype in patients with lung carcinoma will reduce unnecessary radical treatment methods beyond surgery.
