Microscopic analysis (A: hematoxylin-eosin (HE) stain; B, C, D, E, F: immunohistochemical analysis). A: Spindle cells arranged in intersecting fascicles and polygonal cells arranged in sheets grow infiltrating. The cellular nuclei are polygonal (bulky, roundish, and irregular), and the tumor cells show 150 mitoses per 50 high-power fields (HE stain; magnification, ×20). B, C, D, E, F: Immunohistochemical images show positive staining of tumor cells for S-100 but negative staining for c-kit, α-SMA, desmin, and CD34. (B: S-100, C: c-kit, D: α-SMA, E: desmin, F: CD34)
