Recurrent giant retroperitoneal liposarcoma with 10 years follow up. Case report and review of literature

Abstract

Highlights Liposarcomas are a malignant transformation of fat tissue, found in two major subtypes according to their differentiation. Enhanced CT is essential for diagnosis and confirmed by percutaneous large core needle guided biopsies. Surgery remains the standard practice in treating non-metastatic liposarcomas. No clear definition for giant liposarcoma, Only 52 cases reported between 1998 and July 2020. Our patient has the longest reported follow up in the literature of 10 years, with 3 operations and 3 recurrences.
