Figure 5: Low-resolution (a) and high-resolution (b) images of the cellular portion of the tumor demonstrate nests or sheets of epithelioid endothelial cells with abundant eosinophilic cytoplasm forming vascular spaces (arrows). The tumor cells line the spaces in a hobnail “tombstone-like” arrangement. Scattered multinucleated giant cells are also noted (arrowheads).
