Retroperitoneal Sarcoma: Two Case Reports

Abstract: Retroperitoneal liposarcoma is a rare mesenchymal tumor of the retroperitoneum, considered a diagnostic challenge due to the wide variety of clinical presentations, none of which are specific to it. Imaging can be predictive of its presence, but the definitive examination is anatomopathological with the existence of several subtypes impacting the prognosis. Complete resection remains the reference treatment even with a considerable risk of recurrence.
