ALCOHOLIC LIVER DISEASE
It is the term used to describe the spectrum of liver injury associated with acute and chronic alcoholism.
There are three sequential stages:
¤ Alcoholic steatosis (fatty liver)
¤ Alcoholic hepatitis
¤ Alcoholic cirrhosis

ALCOHOLIC STEATOSIS
Grossly:
¤ Liver is enlarged, yellow , greasy & firm with a
smooth
glistening capsule.

Microscopically:
¤ Initial microvesicular droplets of fat in the
hepatocyte cytoplasm followed by
macrovesicular large
droplets of fat displacing the nucleus to the
periphery.
¤ Fat cyst may develop due to coalescence and
rupture
of fat containing hepatocytes
¤ Lipogranulomas (collection of lymphocytes

ALCOHOLIC HEPATITIS
¤ Develops acutely, usually following a bout of
heavy drinking.
Microscopically:
1. Hepatocellular necrosis – single or small
clusters of
hepatocytes , especially in zone 3 undergo
ballooning
degeneration & necrosis.

Also seen in other conditions such as
ø primary biliary cirrhosis
ø indian childhood cirrhosis
ø cholestatic syndromes
ø wilsons disease
ø intestinal bypass surgery
ø focal nodular hyperplasia
ø hepatocellular carcinoma

4. Fibrosis :
pericellular & perivenular fibrosis, producing a web
like or chicken wire like appearance
– creeping collagenosis.
3 . Inflammatory response:
areas of hepatocellular necrosis & regions of
Mallory
bodies are associated with an inflammatory
infiltrate

ALCOHOLIC CIRRHOSIS
Laennec’s cirrhosis , portal cirrhosis , hobnail
cirrhosis , nutritional cirrhosis , diffuse
cirrhosis & micronodular cirrhosis.
Grossly ;
¤ Nodules are tawny yellow in color

¤ Begins as micronodular cirrhosis:
1. Nodules less than 3 mm in
diameter
2. Liver large ,fatty, usually
above 2 kg
¤ Macronodular cirrhosis:

Microscopically:
Nodular pattern- normal lobular architecture is
effaced & replaced with nodule formation.
Fibrous septa- divide hepatic parenchyma to
nodules are initially delicate. As the fibrous
scarring increases with time ,it become dense.

Necrosis , inflammation and bile duct proliferation-
Fibrous septa - sparse infiltrate of mononuclear
cells with
some bileduct proliferation.
Bile stasis & increased cytoplasmic hemosiderin
Hepatic parenchyma- regenerative nodules
are formed. As the thickness of fibrous
septa increase, fat in hepatocyte is decreased.
