We report a rare case of primary mediastinal liposarcoma. A 77-year-old woman, who had undergone removal of a posterior mediastinal lipoma 6 years previously, was referred to our department for non-productive cough and abnormality in her chest roentgenogram.Computed tomography revealed bilateral posterior mediastinal tumors which were homogeneous and showed low attenuation.Two-stage tumor resection was carried out. Pathological study showed that the tumor was a primary mediastinal liposarcoma, Neither radiation therapy non chemotherapy was carried out. Surgical wide en bloc excision is the treatment of choice, and careful longterm follow up is needed.
