Tumor cells stain for the usual vascular and endothelial markers including CD31, CD34, CD144 (VE-cadherin), and at least focally for factor VIII-related antigen. The new marker FLI-1, a nuclear transcription factor, appears to be expressed in almost 100% of different vascular tumors, including angiosarcoma.
The cells are also positive for CD31, factor VIII-related antigen, and vimentin.
Because these tumors arise from endothelial cells, they usually express factor VIII-related antigen and/or ulex europaeus agglutinin-binding protein.
(2-4) Essential to the diagnosis is the positivity of the epithelioid and dendritic cells to at least one of the endothelial markers, such as factor VIII-related antigen (FVIII-RAg), CD34, and/or CD31, with FVIII-RAg being the most frequent.
