Figure 1: (A) Squamous cell carcinoma blends imperceptibly with the sarcoma-like tumor (H and E; ×200). (B) The spindle cell component. Hyperchromatic, pleomorphic nuclei with frequent mitoses are seen (11 o.clock position) (H and E. ×400). (C) Immunoperoxidase staining for pancytokeratin shows strong cytoplasmic positivity within both the scattered spindled cells as well as in the epithelial component (PAP-hematoxylin; ×400). (D) Immunoperoxidase staining for vimentin also shows strong cytoplasmic positivity within both the components (PAP-hematoxylin; ×200)
