Left, Low-power photomicrograph of metastatic Wilms tumor and adjacent lung parenchyma (hematoxylin-eosin, original magnification ×40). Right, High-power photomicrograph of the neoplasm shows the monomorphic population of small round to oval hematoxylinophilic cells with scant cytoplasm and overlapping nuclei with evenly distributed chromatin and small nucleoli, characteristic of the blastema pattern of Wilms tumor. Note mitotic figure in the center of the photomicrograph (hematoxylin-eosin, original magnification ×400).
