Hepatitis C with metavir stage IV fibrosis (advanced fibrosis/cirrhosis) and confluent piecemeal necrosis.  
Inflamed bands cross hepatocytes with steatosis (Row 1 Left 40X). Trichrome shows extensive bridges  (Row 1 Right 40X). Trichrome also documents early nodule formation (Row 2 Left 40X). Reticulin shows regeneration (two nuclei per cord) in a nodule, but not throughout (Row 2 Right 200X). Hematoxylin and eosin shows piecemeal necrosis as inflammatory cells surrounding hepatocytes (Row 3 Left 400X). Reticulin shows black lines about hepatocytes, indicating confluent piecemeal necrosis (Row 3 Right 400X).

Hepatitis C. Metavir Activity Index 2 (PMN2, LN1), Metavir fibrosis stage 3.
Expanded dark triads, indicating interface hepatitis [red arrows], foci of steatosis [green arros], potential bridge [blue arrow] (Row 1 Left 20X). Extending from triad are stretches of apparent necrosis [green arrows], inflammatory cells bound hepatocytes afflicted by piecemeal necrosis [yellow arrows], ballooning degeneration denoted by cytoplasmic tufts [blue arrows] (Row 1 Right 400X). Reticulin shows collapse (necrosis) with thick bands [red arrows], as well as rosettes [green arrows] indicating dilated cholangioles (Row 2 Left 200X). Reticulin here shows continuous piecemeal necrosis with black bounded hepatocyte islets [arrows] (Row 2 Right 200X). Reticulin here shows a bridge with regeneration, wherein two or more nuclei lie between reticulin lines [arrows] (Row 3 Left 200X). Trichrome demarcates one of the bridges (Row 3 Right 200X).
