A 75-year-old male case of a pulmonary blastoma with high serum alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA) levels is reported. A mass shadow in the right lower lung field was visible on examination of a chest X-ray. Serum AFP and CEA levels were 466.1 ng/ml and 5.8 ng/ml, respectively. The autopsy revealed a pulmonary blastoma composed of malignant epithelial and mesenchymal elements. In the epithelial elements, AFP and CEA producing tumor cells were detected by immunoenzymatic labelling (PAP) methods.
