- Diffuse laminar infiltration through large epithelioid cell clusters. Monomorphic epithelioid tumor cells with prominent vesicular nuclei and clearly protruding eosinophilic cytoplasm; recurrent intracytoplasmic vacuoles, occasionally with erythrocytes. Mature vascular lumina are rarely encountered.
- Immunohistology: Vascular markers (factor VIII; CD31) and cytokeratin positive.
- Cytogenetically, the detection of the translocation t(1;39(p36.3;q25) can be diagnostically decisive.
