Morphology and immunohistochemical stainings: (A) H&E (original magnification 100×) and (B) H&E (original magnification 400×) show a spindle cell proliferation in an intraparotideal lymph node with moderate cellular pleomorphy (C) Vimentin (original magnification 400×) and (D)HLA-DR (original magnification 400×) were strongly expressed by the tumor cells. (E) Clusterin (original magnification 400×) and (F) S100 protein (original magnification 400×) were negative in the tumor cells. (G)CD20 showed only very few reactive small B-cells (original magnification 400×) and (H) CD3 some reactive T-lymphocytes (original magnification 400×).
