Comments:
Seminomas may retain immunoreactivity for some markers, such as PLAP, even after necrosis. The left half shows a completely necrotic tumor nodule. The ghost outlines of necrotic cells are visible. The right panel shows retained immunoreactivity for PLAP in tumor cells. Higher magnification of the previous image.
