Figure 2: a) Sarcoma with storiform and fascicles, marked atypia, mitosis, and giant cells. (b) Fleshy white area with atypical spindle stromal cells, tumor giant cells and typical lipoblasts having central nucleus with indentation and abundant vacuolated to clear cytoplasm (Hand E ×400). (c) Dedifferentiated area with well separated normal renal parenchyma (Hand E ×200). (d) IHC: strong vimentin and S100 positivity in dedifferentiated and well-differentiated areas. Lipoblasts are strongly S100 positive (×400). (e) Low and medium. (f) Power view of IVC wall with adherent thrombus and invasion into wall
