Surgical approach on Reccurent Retroperitoneal Liposarcoma with Involvement of Surrounding Organs

Abstract

Background: Retroperitoneal sarcomas are neoplasms that occupy only 0.3 -3% of all solid tumors. Liposarcomas are the most frequent soft tissue sarcomas in adults. Symptoms would only be detected if the liposarcoma infiltrates on the surrounding organs. Case presentation: 58-year-old woman presented with complaints of progressive abdominal distension, loss of appetite, malaise, constipation and weight loss of about 7 kg. Abdominal CT scanning showed the presence of a retroperitoneal tumor that occupied almost the entire right part of abdominal cavity. 16 months earlier, the patient was operated in another surgical facility due to liposarcoma, derived from retroperitoneum (Histopathological finding: Poorly differentiated (G3) liposarcoma pleomorphic cell type). The patient was operated under the diagnosis of retroperitoneal liposarcoma. Conclusions: Treatment of choice is radical surgical procedure including elimination of all the structures and organs involved by the tumour process -RO resection as a basic principle of surgical treatment.
