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

Page 4: Cirrhosis
Page 5: Cirrhosis

ALCOHOLIC STEATOSIS

Grossly:

¤ Liver is enlarged, yellow , greasy & firm with a

smooth

glistening capsule.

Page 6: Cirrhosis

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

l

Page 16: Cirrhosis

¤ Begins as micronodular cirrhosis:

1. Nodules less than 3 mm in

diameter

2. Liver large ,fatty, usually

above 2 kg

¤ Macronodular cirrhosis:

Page 17: Cirrhosis
Page 18: 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.

Page 19: Cirrhosis

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.
