Intracardiac primary fibrosarcoma. Case report and literature review.

A 58-year-old woman was hospitalized because of shortness of breath, cough, weakness, and physical signs suggestive of mitral stenosis. Echo-Doppler examination revealed a left atrial mass. This was removed and turned out to be a fibrosarcoma. Recurrence of the tumor with metastases into the pericardium, thyroid goiter, and left kidney led to the patient's death 6 months later. The clinical and pathological features of our rare case are compared with those in the literature.
