Figure 2: (a) Microscopy showed a cellular tumor in diffuse sheet with interspersed staghorn-shaped blood vessel (H and E, ×100) (b) The individual cells showed spindle-shaped nuclei, nuclear grooving, and bland chromatin (H and E, ×400) (c) Interspersed were erythroid colonies (black arrow) and megakaryocytes (blue arrow) (H and E, ×100) (d-f) Positive immunohistochemistry for CD99 (membranocytoplasmic, ×200, d), CD34 (membranous, ×200, e), and STAT6 (nuclear, ×400, f)
