Retroperitoneal liposarcoma: A case report

Introduction: We report an interesting case of a 67-year-old female presented with symptomatic cholelithiasis and was found to have an occult retroperitoneal sarcoma on work up. Case Report: A 67-year-old female was referred to the surgery clinic by the gynecology service for symptomatic cholelithiasis. On examination, she was moderately obese with mild right upper quadrant tenderness and a reducible incisional hernia. An abdominal ultrasound revealed cholelithiasis and a left retroperitoneal flank mass. She was referred for abdominal computed tomography scan and magnetic resonance imaging scan which revealed a large left retroperitoneal cystic mass adherent to the left kidney. She underwent en-bloc resection of retroperitoneal tumor, cholecystectomy, and repair of incisional hernia. Her postoperative course was uneventful and she continues to do well without adjuvant chemoradiation. Discussion: One-third of malignant tumors located in the retroperitoneum are sarcomas. The median age of presentation occurs in the sixth decade. As with our patient complete surgical resection is the optimal treatment for patients. The addition of adjuvant radiation therapy to surgical resection is associated with both a reduced risk of local recurrence and a longer recurrence-free interval, but it does not improve overall survival. Conclusion: The review of the literature emphasizes that the management of retroperitoneal sarcomas consists of complete resection of the tumor with adjuvant radiotherapy (if the tumor is high grade) combined with surveillance for early liposarcoma detection of recurrence or metastases.
