Feasibility of laparoscopic isolated caudate lobe resection for rare hepatic mesenchymal neoplasms

Figure 2 Left approach to laparoscopic caudate perivascular epithelioid cell neoplasm lobectomy. A and B: The tumor was located at the Spiegel’s lobe; C: Isolation of the caudate lobe from left side; D: Dissection of the feeding portal pedicle of the caudate lobe (arrow P); E: Isolation of the tumor (arrow T) and dissection of short hepatic vein (arrow SHV); F: Surgical area after the tumor was resected; G: Microscopic appearance of caudate perivascular epithelioid cell neoplasm (×200); H: Positive HMB-45 staining by immunohistochemistry (×200).
