BACKGROUND: Retroperitoneal liposarcoma is a rare tumor that may grow to a considerable size before causing clinical symptoms. Mixed-type retroperitoneal liposarcoma is a very rare clinical entity. METHODS: We herein describe a rare case of a 54-year-old female who was diagnosed with a giant retroperitoneal liposarcoma arising from the right perinephric space. RESULTS: Radical nephrectomy and right salpingo-oophorectomy were necessary to achieve complete tumor excision. Histological examination revealed a mixed-type liposarcoma consisting of well-differentiated and pleomorphic elements and deep invasion into the renal parenchyma, which is quite infrequent. The patient was well and disease-free 12 months after surgery. CONCLUSIONS: Mixed-type retroperitoneal liposarcoma is a rare tumor. Aggressive surgical resection of the tumor together with adjacent structures, if necessary, is the mainstay of treatment.
