Figure 3: Photomicrographs of the tumor showing immunohistochemical profile of diffuse strong positivity for CD31 [(a) immunohistochemistry (IHC), ×400 inset highlights the positivity of vacuolated cells for CD31], CD34 [(b) IHC, ×400 inset highlights the positivity of vacuolated cells for CD34], and Fli-1 [(c) IHC, ×200]. Focal areas of tumor show positivity for epithelial membrane antigen [(d) IHC, ×200] and cytokeratin [(e)IHC, ×200]
