Cytologic features immunocytochemical findings and DNA ploidy in four rare cases of epithelioid hemangioendothelioma involving effusions

摘要

Background:Epithelioid hemangioendothelioma (EHE) involving serous effusion is extremely rare, and the diagnosis can be challenging. DNA ploidy quantitation of EHE in effusion fluids has not been previously described in the English-language literature.
