Retroperitoneal liposarcomas are rare malignant tumors known for their slow growth and challenging management, particularly due to their substantial size upon diagnosis. This case report highlights a remarkable instance of a massive retroperitoneal sarcoma concomitant with synchronous renal cell carcinoma. We report a 57-year-old male patient with a huge abdominal mass hampering his daily activities and on further investigation, CECT abdomen and pelvis revealed a large Retroperitoneal Scarcoma (RPS) occupying his entire abdominal cavity displacing the visceral organs. In accordance with the final decision of the multi-disciplinary team meeting, he was subjected for surgery and the tumor was excised enbloc. He is kept under surveillance. Surgery remains the main modality of treatment for RPS. Hence careful preoperative surgical planning and execution with meticulous dissection aids in achieving a good clinical outcome and to reduce recurrence in future. Despite the huge size of the tumor, surgical intervention remains the primary treatment option whenever feasible, often complemented by additional therapeutic approaches. •Retroperitoneal liposarcomas (RPS) are slow growing rare tumors with late presentation in advanced stage.•Surgical intervention becomes challenging in view of huge size and proximity with vital structures in the retroperitoneum.•Preoperative surgical planning with the aid of imaging modalities and meticulous dissection plays a key role in achieving enbloc resection.•Multi-disciplinary team approach should be considered to emphasis patient safety and to overcome the therapeutic challenge.
