case_images: Pathology confirmed a retroperitoneal high-grade pleomorphic liposarcoma involving the right adrenal gland and extending into the right lobe of the liver (Figure 2(a)), measuring 21 cm in size and with negative margins. There was 30%-40% tumor necrosis present, no lymphovascular invasion identified, and 30 mitoses per 10 high-power fields (Figure 2(b)-(c)). The specimen stained positive for vimentin only, but was negative for S100, desmin, SMA, hepatocyte antigen, arginase, HMB45, MiTF, caldesmon, and calponin.
