Liposarcoma Retro-Peritoneal in the General Surgery Department of the Hospital of the District of the Commune IV

Retroperitoneal soft tissue sarcomas in the retroperitoneal/intra-abdominal regions represent 10% - 15% of all cases of soft tissue sarcoma. Liposarcomas, which are the most common histological type, account for 20% - 45% of retroperitoneal/intra-abdominal sarcoma cases, and 20% of liposarcomas cases are primary retroperitoneal liposarcomas. Surgical resection in case of malignancy remains the treatment of choice for liposarcomas, according to the guidelines of most major international companies. Our goal was to improve the management of retroperitoneal liposarcoma. This was a 65-year-old patient, with no medical or surgical history, who was referred to us for abdominal swelling, in whom clinical and paraclinical examination found retroperitoneal liposarcoma stage IV, and the surgical treatment consisted in making a tumor reduction. Conclusion: Retro-peritoneal liposarcoma is an undervalued malignant tumor, and the diagnosis is often late.
