case_images: The nuclei were vesicular and contained nucleoli; mitoses were numerous with 5 mitoses per high-power field; and scattered foci of necrosis were present (Figure 1). Immunohistochemistry was positive for S100 and CD68 and negative for keratin, EMA, CD34, MART1, and synaptophysin (Figure 1). The proliferation rate assessed by the KI-67 stain was 25% (Figure 1).
