Giant retroperitoneal liposarcoma with left renal involvement, a case report at the "San Francisco de Quito" hospital

Abstract

Liposarcomas located in the retroperitoneum are usually low and intermediate grade lesions. The predominant symptoms are related to the mass effect. In imaging studies, with and without contrast tomography showed adequate sensitivity. Surgical therapy is the only therapy that offers potentially curative benefits when complete resection with clear margins is performed. The objective of this study was a female patient, 40 years, whose complaint was vaginal itching, mild abdominal pain at the level of umbilicus and dyspareunia, initially treated for recurrent vaginosis by persisting with abdominal pain tomography showed hypodense retroperitoneal mass region that surrounds the kidney and collecting system on the left side. Laparotomy was performed and double J stent placement, the procedure was exeresis more left nephrectomy retroperitoneal mass. Histopathology reported low grade liposarcoma with free resection edges. In this time, tomographic controls are negative for recurrences. Radical surgical treatment of soft tissue tumors has shown a favorable outcome. In this case, the outcome has been similar to those reported in studies of radical exeresis. Early detection and multidisciplinary management can provide a curative therapy.
