The authors present surgical treatment of 9 kg liposarcoma of the retroperitoneum. These mesenchyme tumors are rare in population. They represent less than 0.1 % of all tumors. Among 13 % of them is localized in the retroperitoneum. Prerequisite to make the therapeutical strategy is to determine its relation to surrounding organs on basis of precise preoperative examination together with preoperative histologisation of the tumor by biopsy together with ultrasonography or CT control. Radical extirpation of the tumor is considered as the fundamental therapeutic procedure.
