title: [Primary cardiac malignant fibrous histiocytoma in 47-year-old woman].
abstract: A case of pleomorphic malignant fibrous histiocytoma of the right atrium and right ventricle is presented. Primary cardiac malignant fibrous histiocytoma (MFH) is extremely rare and its etiology and clinical course are not precisely known. We treated a 47-year-old female patient with persistent fever and cough, shortness of breath and anasarca. The patient died after eight months with symptoms of cardiac shock. Autopsy revealed a big soft yellow tumor in the right heart. Microscopically, atypical fibroblast-like cells, pleomorphic and multinucleated giant tumor cells with eosinophilic cytoplasm were observed within the myxoid and fibrous stroma. Immunohistochemically, tumor cells were positive for alfa-1-antitrypsin and partially positive for CD68 and vimentin. According to histopathologic and immunohistochemical features we diagnosed pleomorphic MFH.
