[pleomorphic liposarcoma]

The patient was 70 -year -old man . He had complained of general fatigue and hoarseness for 5 months . Chest computed tomography scan demonstrated a large anterior mediastinal tumor . The diagnosis of high grade malignant sarcoma was established with needle biopsy and the complete resection through median sternotomy was conducted . The tumor was histopathologically diagnosed pleomorphic liposarcoma . Six months after operation , right supraclavicular lymph node metastasis was noted . Radiotherapy was performed , but the liver metastasis appeared subsequently 16 months after operation . Pleomorphic type is considered one of the poorest prognostic liposarcoma and should be required special attention .
