  Figure 3. Evaluation of pathology samples in terms of desmin involvement and pleomorphism (x20). (a) Desmin-negative result supporting the diagnosis of a primary cardiac epithelioid hemangioendothelioma is characterized by brown non-staining of the sample. (b) Primary cardiac epithelioid hemangioendothelioma is characterized by moderate pleomorphism, and atypically located cells and nucleus.
