Malignant Solitary Fibrous Tumor of the Left Ventricular Epicardium

Reports describing solitary fibrous tumors of the pericardium are rare. Surgical treatment was performed on a 49-year-old woman with a large pericardial mass. The mass was attached to the left ventricular wall with a broad stalk and was free of the parietal pericardium. It was apparent macroscopically that the tumor had invaded the left ventricular muscle. On histopathology, the tumor was diagnosed as a solitary fibrous tumor with low-grade malignancy.
