FIGURE 3 Mesenchymal component of the pulmonary blastoma in the chest wall, resected in May 2004, showing frequent apoptotic bodies (black arrows), solid sheets of small cells with scant cytoplasm, and round to slightly elongated nuclei with clumped chromatin and small nucleoli. Hematoxylin and eosin staining; original magnification ×400.

FIGURE 4 Fetal adenocarcinoma component of the pulmonary blastoma in the chest wall resected in May 2004, with glands lined by pseudostratified columnar epithelium with sub- and supranuclear vacuoles. Hematoxylin and eosin staining; original magnification ×400.

FIGURE 5 Fetal adenocarcinoma component of the pulmonary blastoma in the chest wall resected in May 2004, showing diffuse positive nuclear immunostaining for TTF-1, a pulmonary marker.

FIGURE 6 Metastatic pulmonary blastoma in the right kidney resected in April 2006 with morphological correspondence to the fetal adenocarcinoma from the chest wall (lower half of field) and squamous differentiation (upper half of field) but no embryonic mesenchyme component. Hematoxylin and eosin staining; original magnification ×400.
