Giant retroperitoneal liposarcoma treated with radical conservative surgery: A case report and review of literature

Figure 1 Preoperative image and computed tomography scan. A: Preoperative image, the patient was initially diagnosed with a left inguinal hernia; B: Preoperative computed tomography scan. A giant retroperitoneal liposarcoma occupied the entire left abdominal cavity with extreme lateralization of the bowel and the left kidney. A grade III hydronephrosis was evident.

Figure 2 Surgical specimen. A completely encapsulated liposarcoma was entirely removed without any surrounding organ damage.

Figure 3 Postoperative computed tomography scan. The intra-abdominal organs resumed their physiological positions. A: Computed tomography (CT) scan at the level of the celiac trunk; B: CT scan at the level of the left renal vein.

Figure 4 Pathologic picture of well-differentiated liposarcoma. A: Atypical stromal cells (black arrows; mandatory for diagnosis of well-differentiated liposarcoma) and collagen ropey bands (blue arrow; enhance diagnostic confidence) are present; B: Lipoblastic cell (green arrow).
