Figure 1 Focal nodular hyperplasia. A: Fibrous septa (green) giving a nodular appearance to liver parenchyma. Masson’s trichrome staining; original magnification × 40; B: Diffuse CD34 positive immunostaining in the sinusoids; original magnification × 100.

Figure 2 Hereditary hemorrhagic telangiectasia. Liver parenchyma, devoid of fibrous intra-parenchimal septa, with widespread angiectases in portal and peri-portal areas. A: Hematoxylin-eosin staining; original magnification × 100; B: Hematoxylin-eosin staining; original magnification × 200; C: Masson’s trichrome staining; original magnification × 400.

Figure 3 Primary biliary cirrhosis. A: Intra-portal granuloma. Hematoxylin-eosin staining; original magnification × 200; B: Portal immunoglobulin M (IgM) lymphoplasmacytic infiltrate and bile duct damage. IgM immunostaining; original magnification × 400; C: Absence of cytokeratin 7 (CK7) positive bile ducts in some portal tracts. CK7 immunostaining; original magnification × 200.

Figure 4 Magnetic resonance. A: Fat saturation gradient echo T1-weighted hepatic arterial phase magnetic resonance (MR) shows multiple ill defined hypervascular areas in the the right liver lobe, due to arterovenous shunts, and a round, clearly visible, 3 cm lesion surrounded by a hypointense halo; B: On hepatobiliary phase MR, arteriovenous shunt are no longer visible, while lesion, proven to be focal nodular hyperplasia at core biopsy, is hyperintense in comparison to surrounding liver parenchyma.
