Abstract


Retroperitoneal liposarcoma is a rare malignant mesenchymal tumor with an annual incidence of approximately 2.5 cases per 100,000 inhabitants. It does not present specific symptoms, so its early diagnosis is difficult and in most cases it is performed when it has a large size. A 45-year-old patient with a history of increased abdominal perimeter and local discomfort was admitted in our center. After performing an abdominopelvic CT, she was diagnosed of a large, bulky tumor of lipomatous origin that significantly displaced the intestinal loops and the rest of neighboring organs. In view of the clinical suspicion of a liposarcoma, the patient underwent a resection of the lesion located in the retroperitoneum. The histopathological study determined a well differentiated retroperitoneal liposarcoma. The well-differentiated liposarcoma located in the lower limbs and the retroperitoneal space. Its age of presentation is between the fourth and sixth decade of life without finding differences between men and women. Its treatment is surgical and involves the resection of the tumor mass with non-affected surgical margins. Retroperitoneal liposarcoma is a malignant tumor whose treatment is fundamentally surgical. These tumors tend to be resistant to radiotherapy and / or chemotherapy. Among the most important prognostic factors related to survival is surgery with non-affected margins.
