Microphotograph shows intersecting marginated groups of spindle tumor cell with elongated and blunt-ended nuclei. There is nuclear hyperchromasia and pleomorphism. ((a) H&E 100x, (b) 200x). The cells are immunopositive for smooth muscle actin ((c) IHC (SMA) 200x) and focally positive for S100 ((d) IHC (S100) 200x).
