Retroperitoneal sarcomas are rare tumors and form 15% of all soft tissue sarcomas. The most common histologic type of retroperitoneal sarcomas is liposarcoma, which are frequently diagnosed incidentally. Major treatment in retroperitoneal liposarcoma is extensive surgical resection. Because of the risk of local recurrence and metastasis after surgery, these patients should be followed up by multidiciplinary for a long time. Postoperative follow-up of the patients should be multidisciplinary. Herein we presented our approach to a 72-year-old liposarcoma case, who was admitted without follow-up after the first ope- ration and was presented with a giant retro- peritoneal mass of 24 cm 16 years later.
