I. Microspecimens:

89. Acute massive necrosis of liver. (H.E. stain).

Indications:

1. The extensive area of necrosis (tissue debris) in the center of the liver lobule.

2. The inflammatory infiltrate in the area of necrosis.

3. Fatty degeneration of hepatocytes at the periphery of the lobule.

209. Acute viral hepatitis. (H.E. stain).

Indications:

1. Vacuolar degeneration of hepatocytes at the periphery of the lobule.

2. Lymphocytic and plasmacytic infiltration of portal tracts.

37. Liver micronodular cirrhosis. (pycrofuxin by van Gieson method stain).

Indications:

1. Thin bundles of connective tissue in the liver lobules, which join together the central veins with portals

vessels.

2. "Pseudolobules".

157. Hepatocellular carcinoma on the background of liver cirrhosis. (H.E. stain).

Indications:
