Cardiac angiosarcoma. Histological, immunohistochemical and ultrastructural study.
A case of cardiac angiosarcoma of the right atrium in a man aged of 41 years is described. The immunohistochemical methods showed a positivity for Factor VIII, Vimentin, Lectin UEA1 and very poor reactivity for a histiocytary markers. Electron microscopy confirmed the endothelial differentiation of some tumour cells. The relations between genuine cardiac angiosarcomas, malignant fibrous histiocytomas, and Kaposi's sarcomas arising in the heart are discussed.
