ABSTRACT
Retroperitoneal liposarcomas are malignant mesenchymal tumors that develop from fat cells in the retroperitoneal space. They are primitive and independent of the organs in this space, sometimes invading the kidney. They are rare and have benefited from imaging techniques, in particular ultrasound, CT and MRI. However, these tumors still pose diagnostic and therapeutic problems, they are often diagnosed as a palpable mass. The reference treatment is complete tumor resection with healthy margins and without invasion. For this purpose, some authors recommend an extension to the proximal organs. However, the anatomical constraints of the retroperitoneal space and the often large tumor volume limit the possibilities of achieving satisfactory clearance.
