Kidney Sparing Huge Retroperitoneal Liposarcoma

Abstract

Retroperitoneal Liposarcoma is a rare malignant tumor of mesenchymal origin and is the most common type of soft tissue sarcoma with a rate of 3-4 individuals for every million people. It usually appears between 50-70 years of age, and the proportion between the sexes are equal. Due to their retroperitoneal location they are much more difficult to diagnose and often came into notice as incidental findings when they became very large or start to invade adjacent organs. The Gold Standard treatment of Retroperitoneal Liposarcoma is resection as per the European Society for Medical Oncology guideline (ESMO). Chemotherapy and radiotherapy can be offered as palliative treatment because of the extremely massive size of primary tumors rendering them inoperable as well as in high-grade cases. In this case study, a case of 40 years old male was reported, who underwent surgical resection of retroperitoneal liposarcoma. The complete resection of the mass was successful and the kidney was spared in the procedure. Keywords: Retroperitoneal Liposarcoma; Multimodality Treatment; Chemotherapy; Radiotherapy.
