Histopathological diagnosis is readily made when more differentiated squamous component is identified, with a predominant sarcomatous appearance in the deeper areas of the tumor. Immunohistochemically, neoplastic cells express a strong positivity for both low and high weight cytokeratins in the squamous areas; and spindle-cell component, not only expresses those cytokeratins, although with variable intensity, but also vimentin. Ultrastructural study confirms the epithelial nature of the neoplasia in the spindle-cell component.
Dr. Ana Puig Rullán is pathologist and manager of the Cytology section in the Complejo Hospitalario de Ciudad Real.
