RESUMO
Primary cardiac sarcoma is rare, and there have been only a few reports on its cytologic findings. Myxofibrosarcoma, a variant of fibrosarcoma of the heart, is an extremely rare entity. We present a case of primary cardiac myxofibrosarcoma in a 63-year-old woman. Pleural fluid cytology and imprint cytology of the resected tumor at operation and autopsy were obtained. Cytologic evaluation with immunocytochemical staining utilizing a cell transfer technique revealed that tumor cells of the resected tumor and autopsy specimen and pleural effusion demonstrated large and pleomorphic cells with irregular, hyperchromatic nuclei and were positive for vimentin. Combination of morphology and immunoprofile of the cells of pleural effusion was compatible with the diagnosis of metastatic myxofibrosarcoma. Diagn.
