Mediastinal Myxoid Liposarcoma with Intrapericardial Involvement and Large Pericardial Effusion.
Liposarcoma is the name given to a group of soft tissue sarcomas (STSs) with adipocytic differentiation. As a group, liposarcomas are the second most common STSs in adults. In 1951 Kozonis et al published that in the English language only four cases of liposarcomas originating in the mediastinum had been described. Primary mediastinal liposarcoma is an uncommon neoplasm of intrathoracic origin. We present the case of a 47-year-old woman diagnosed with a large mediastinal mass with intrapericardial invasion and massive pericardial effusion; biopsies showed a mediastinal liposarcoma.
