Figure E . Low power view of the cut surface of the lesion through the central fibrous scar. The fibrous septae radiate from the central scar dividing the surrounding hepatocytes into lobules. Figure F . A proliferation of bile ductules is seen among hepatocytes in the adjacent area of the scar.
Vessels are prominent throughout the lesion but are most abundant in the fibrous scar.
