Abstract
BackgroundLiposarcoma is the most frequent histopathological variety of the retroperitoneum, surgery is the gold standard for treatment.Case presentationWe present the case of a 24-year-old male who was diagnosed with a giant retroperitoneal liposarcoma. The patient received palliative treatment due to non-resectability on the basis of chemotherapy. We decided to perform surgery after no benefit was received with systemic treatment. Complete macroscopic resection of the tumor was performed, without multi-organ resection. The patient is currently alive and disease free at 14 months of evolution.ConclusionRetroperitoneal liposarcomas represent a unique situation and require a more aggressive surgical approach including multiple resections for recurrences. Based on the ability of the patient to tolerate the procedure, surgery is suggested to evaluate resectability of the tumor. We must take into consideration whether prolonged survival will be attained and tumor removal will result in palliation of symptoms.

Summary
Liposarcoma is the most frequent histopathological variety of the retroperitoneum, surgery is the gold standard for treatment.Case presentation: We present the case of a 24-year-old male who was diagnosed with a giant retroperitoneal liposarcoma. Liposarcoma is the most frequent histopathological variety of the retroperitoneum, surgery is the gold standard for treatment. Liposarcomas are neoplasms of mesodermic origin derived from adipose tissue and correspond to 10–14% of all soft tissue sarcomas. They represent < 1% of all malignant tumors [1,2]. The most frequent subtypes are liposarcoma (41%), leiomyosarcoma (28%), malignant fibrous histiocytoma (7%), fibrosarcoma (6%) and tumors of the peripheral nerve sheath (3%) [3]. Liposarcoma is the most frequent histopathological variety of the retroperitoneum [2]. It presents with inherent characteristics in relation to its deep localization and slow expansive growth. The objective of this study is to report a case of giant retroperitoneal sarcoma
