title: Seaweed floating in the pericardium: a rare case of primary dedifferentiated liposarcoma.
abstract: Primary cardiac tumors are uncommon and primary liposarcoma of the pericardium is extremely rare. We describe the case of a 55-year-old Caucasian woman without significant medical history, who presented with 3weeks complain of dyspnea, peripheral edema, and gain weight. Echocardiography revealed a huge pericardial mass confirmed by computed tomography and by magnetic resonance. The lesion was primitive of the pericardium but the surgery was not able to cut it off because of the absence of cleavage planes. Histopathologic analysis detected a dedifferentiated liposarcoma. Mediastinum compression syndrome brought the patient to the exitus in a few days.
