Primary pulmonary liposarcoma--a case report.

Liposarcoma of the lung is an extremely rare disease with less than 10 cases reported to date. A case of a locally advanced, pulmonary mixed liposarcoma in a 49-year-old male is presented here. Left pneumonectomy with radical lymph node dissection was performed. The postoperative course was uneventful and no recurrence or metastasis was observed for 3 years. Although liposarcoma of the lung is classified as an aggressive, highly metastatic disease, complete resection may result in disease-free survival.
