Figure 5: (a) Histopathology of resected tumor mass showing spindle cell proliferation with interspersed highly pleomorphic large cells. (b) The tumor cells show focal weak positivity for CD56. (c) On immunohistochemistry, the tumor cells are positive for smooth muscle antigen. (d) Strong nuclear positivity for SATB2
