[Diagnosis and treatment of primary mediastinal liposarcoma].

Mediastinal liposarcoma are of rare entity; there are less than one hundred cases published worldwide. Because of the equivocal and inapparent symptomatology clinical signs often are falsely estimated, and in time of surgery there is generally seen a wide spread tumor growth, so that a radical resection often is impossible. Radiotherapy and chemotherapy are of limited value and mean no chance for curative therapy. The case of a 46 years old patient with an extensive primary liposarcoma of the mediastinum and the results of the review of the literature will be discussed.
