A, Sheet-like small vascular spaces are filled with erythrocytes and surrounded by hemosiderin (hematoxylin-eosin, original magnification ×100). B, Large, polygonal cells show vesicular nuclei, conspicuous nucleoli, and mitotic activity (hematoxylin-eosin, original magnification ×400). C, Tumor cells showed positive results for CD31 (immunohistochemical stain, original magnification ×400). D, Neoplastic cells showed immunoreactivity for FVIII (von Willebrand factor) (immunohistochemical stain, original magnification ×400).
