Retroperitoneal liposarcomas often have a delayed onset of symptoms and appear as a huge tumor when it is detected. We describe here a patient with retroperitoneal liposarcoma who underwent four resections due to recurrences and is still doing well. A 79-year-old woman was admitted to the hospital because of abdominal distension and pain in October 1992. A computed tomography revealed a large solid mass, 40cm in diameter, located in the retroperitoneal space, which was resected surgically. The resected material was 10kg in weight. Histpathologically it was diagnosed as liposarcoma.<br> Subsequently, follow-up studies detected local recurrences of liposarcoma in the retroperitoneum. Except the first operation, a total of three curative operations were performed in January 1996, Nobember 1996 and August 1997, respectively. Surgical materials were about 10cm in size locating in the pelvic cavity; 20cm in size and 2kg in weight; and 14cm in size and 0.4kg in weght, respectively. The patient is still alive as of 5 years after the first operation and is followed on an ambulant basis. Surgical resection is the treatment of choice for liposarcoma, and we to have to deal with recurrence of liposarcoma surgically.
