Histopathological features of renal eAML. Haematoxylin and eosin staining. A The arrowhead indicates the necrosis in a renal eAML sample. Magnification 100 × . B In renal eAML cases, tumors were composed of epithelioid endothelial cells. The arrowhead indicates hyaline degeneration of the vascular wall. Magnification 100 × . As shown by Arrowhead, compared with cells displaying mild nuclear atypia C, cells with severe nuclear atypia (D) are characterized by their larger size, abundant eosinophilic cytoplasm, and nuclear polymorphism. Magnification 400 × . E Renal eAML also displayed atypical mitotic figures (arrows). The higher atypical mitotic figure may associate with malignant behaviors. Magnification 400 × . F Arrowhead indicates the Multinucleated giant cell. Magnification 200 ×
