Introduction: Retroperitoneal liposarcomas are unusual tumors. Their biological and clinical features different from other retroperitoneal sarcomas.
Aim: To analyze our series of retroperitoneal liposarcomas.
Patients And Methods: Retrospective study of 10 patients with retroperitoneal liposarcoma diagnosed in the last 16 years at our institution. Symptoms, diagnosis, treatment and prognosis were analyzed.
Results: Radical resection was done in all cases. Postoperative mortality was 10%. Complementary treatment was considered in each patient. Recurrent disease occurred in 8 patients (14 recurrences), during follow up. In 42% of them recurrences were resected. Actuarial 5-year survival rate was 44%.
Conclusion: Poor prognosis of retroperitoneal liposarcoma is due to its high recurrence rate.

Dedifferentiated liposarcoma (DDLPS) is a nonlipogenic sarcoma arising in association with well-differentiated liposarcoma (LPS), and represents 10% of liposarcomas. Most of the cases of dedifferentiated liposarcoma arise in the retroperitoneal region, followed by deep soft tissue of the extremities, trunk, mediastinum, spermatic cord, and the head and neck region. We report a case of a 35 year old male patient who had DDLPS of the left parotid gland.
