The infiltrate of medium-sized blastic cells with perinuclear microvacuoles (“pearl neckless”), eccentric nuclei, fine chromatin texture, and few nucleoli is demonstrated on the upper three panels (Wright Giemsa stain, ×50 magnification). H&E and immunohistochemical staining findings are demonstrated in the lower 6 panels (×20 magnification).
