Fig. 2From: Angiogenic inflammation and formation of necrosis in the tumor microenvironment influence patient survival after radical surgery for de novo hepatocellular carcinoma in non-cirrhosisDetection of histologic tumor necrosis and infiltrating TIE2-expressing monocytes (TEMs) in hepatocellular carcinoma (HCC) specimens. Arrows indicate positive staining for TEMs (simultaneous red and brown staining) and diamond signs indicate tumor necrosis.
