Figure 2: (a) Skin biopsy showing anastomosing vascular structures in the dermis lined by plump endothelial cells with marked cellular and nuclear polymorphism dissecting the collagen bundles (H and E, ×200). (b) Immunohistochemistry studies showing tumor cells expressing CD31 (DAB Immunostain against CD31 antigen, ×200) (c) Immunohistochemistry studies showing tumor cells negative for CD34 (DAB Immunostain against CD34 antigen, ×200) (d) MIB1 marker study showing low proliferation index around 2% - 3% favoring low grade angiosarcoma (DAB Immunostain against MIB1 antigen, ×400)
