Background: Retroperitoneal sarcomas are neoplasm that are only 0,3-3% of all solid tumors. Liposarcomas is most freguent soft tissue sarcomas in adults. Symptoms would only be detected if the liposarcoma presses on the surrounding organs.
Case presentation: A 58-year-old woman presented with complaint 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 occupies almost the entire right part of abdominal cavity. 16 months earlier, the patient was operated in another surgical facility due to liposarcom, 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.
