Fig. 2From: Clinically aggressive pediatric spinal ependymoma with novel MYC amplification demonstrates molecular and histopathologic similarity to newly described MYCN-amplified spinal ependymomasHistologic features of the primary tumor assessed by routine Hematoxylin and Eosin stain demonstrating perivascular pseudo-rosettes surrounding capillaries showing a microvascular proliferation (20× magnification), with b focal clear cell ependymoma (20× magnification). c Mitotically active cells are denoted by the asterisk (*) (40× magnification). The tumor cells demonstrated d strong perivascular GFAP (20× magnification), e sparse Olig-2 nuclear staining (20× magnification), and f dot-like EMA reactivity (40× magnification). The histopathologic findings were similar in the primary and recurrent tumorsBack to article page
