Hemochromatosis with cirrhosis..
Fibrous bands dissect hepatocyte nodules (Row 1 Left 20X). Iron stain shows 4+ iron, identifiable at the lowest magnification, as well by naked eye (Row 1 Right 20X) This nodule has occasionally enlarged nuclei, which should not be considered dysplasia in and of itself. Note associated relatively inflammation free band with proliferated bile ductules. (Row 2 Left 400X). Reticulin stain shows two cell thick regenerative cords with sinusoidal black lines lacking orientation (Row 2 Right 400X).

Grading (0-4):  
===Grading===
The quantity of iron is scored as follows:  
*0 = none.  
*0 = none.  
*1: only at high power.  
*1: only at high power.
