Key difference between acute hepatitis and chronic hepatitis

A

Acute hepatitis has LESS inflammation and more hepatocyte death than hepatitis. Chronic hepatitis has DENSE mononuclear portal infiltrates and in time, fibrosis. The type of inflammatory cell is not useful because they all invoke a T cell-mediated immunity (mononuclear infiltrates, usually), unlike in other tissues where acute usually has neutrophils (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 606

150
Q

How does one differentiate autoimmune hepatitis from viral hepatitis histologically?

A

There is an early phase of severe cell injury and inflammation followed by RAPID SCARRING. In viral heaptitis, fibrosis takes years or decades to accumulate. There is also an abundant PLASMA CELL infiltration in autoimmune hepatitis. SEE SLIDE 16.19. (TOPNOTCH)Robbins Basic Pathology, 9th ed, p 615

151
Q

Pattern of scarring is distinctive in this liver disease. It starts with central vein sclerosis, then moves outward in a chicken wire fence pattern, creating a central-portal fibrous septa. Ultimately leads to the classic micronodular or Laennec cirrhosis.
