This is the authors' abstract. We don't add key points for this paper.

A rare clinical observation of a patient with a giant retroperitoneal liposarcoma. A 62-year-old patient presented with complaints of a tumor in the abdominal cavity. On CT with IVC, a 214/158/220 mm mass was diagnosed in the retroperitoneal space on the right. The tumor was removed without resection of surrounding organs. Histological examination verified a dedifferentiated liposarcoma. The postoperative period was uncomplicated. Giant retroperitoneal liposarcoma is an extremely rare tumor with a high frequency of recurrence, which depends on several factors, such as the histological type of the tumor, its degree of malignancy, and the radicality of tumor removal. In this case, an R0 resection was performed without resection of surrounding organs.
