## Direct answer

Cirrhosis is the end stage of chronic liver injury: diffuse fibrosis with regenerative nodules that destroy normal hepatic architecture and bridge portal tracts to central veins with portosystemic shunting. Micronodular cirrhosis, with nodules under 3 mm, typifies alcohol and metabolic disease; macronodular cirrhosis with larger, uneven nodules follows chronic viral hepatitis; mixed patterns are common as disease evolves. Whatever the cause — viral, alcohol, fatty liver, biliary, autoimmune or metabolic — the consequences are the same: portal hypertension with varices and ascites, hepatocellular failure with coagulopathy and encephalopathy, and heightened hepatocellular carcinoma risk.

## What you must remember

- **Definition:** irreversible (in structural terms) diffuse process of fibrosis plus nodular regeneration, hepatocyte collapse and vascular rearrangement, stellate cells transdifferentiated into collagen-secreting myofibroblasts.
- **Micronodular (Laennec):** uniform nodules below 3 mm — alcoholic liver disease and metabolic storage diseases such as haemochromatosis.
- **Macronodular (post-necrotic):** nodules above 3 mm of varied size — chronic hepatitis B and C, autoimmune hepatitis and Wilson disease; mixed cirrhosis when longstanding.
- **Indian context:** chronic hepatitis B and C and alcohol remain major causes, while metabolic-associated fatty liver disease is rising steeply; biliary cirrhosis from primary biliary cholangitis or primary sclerosing cholangitis leaves a green, cholestatic liver.
- **Complications of portal hypertension:** oesophageal and gastric variceal bleeding, congestive splenomegaly with hypersplenism, ascites with spontaneous bacterial peritonitis risk, and portosystemic encephalopathy.
- **Complications of hepatocellular failure:** hypoalbuminaemia with oedema, coagulopathy from synthetic failure, jaundice, hyperoestrogenaemic features — spider naevi, palmar erythema, gynaecomastia — and hepatorenal and hepatopulmonary syndromes.
- **Assessment and surveillance:** Child-Turcotte-Pugh scoring (bilirubin, albumin, prothrombin, ascites, encephalopathy) and MELD for transplant priority; six-monthly ultrasound with alpha-fetoprotein for hepatocellular carcinoma surveillance per current guidance.

## Common confusion

Micronodular versus macronodular turns on nodule size and cause — small and uniform with alcohol, large and irregular with viral hepatitis — but any cirrhosis can evolve into a mixed pattern, so answer from the dominant aetiology. Cirrhosis is a response to injury, not a disease itself: every stem hides a cause that must be named, from HBsAg positivity to antimitochondrial antibody. Finally, remember that fibrosis can stabilise with aetiology-directed treatment, but the established nodular architecture does not reverse.

## Exam-focused takeaway

Questions give a stigmata photograph — spider naevi, caput medusae, ascites, Dupuytren contracture in alcoholics — or a gross liver photograph with micronodules, then ask the aetiology. One-liners test the Child-Pugh components, the stellate cell as the fibrogenic engine, and surveillance intervals for hepatocellular carcinoma. Tie each cause to its nodule size, and each complication to portal hypertension or failure.

## Frequently asked questions

### How is cirrhosis defined pathologically?

Diffuse fibrosis with regenerative nodules replacing normal lobular architecture, producing vascular shunts between portal and hepatic veins.

### What separates micronodular from macronodular cirrhosis?

Nodules under 3 mm, uniform, typical of alcohol and metabolic disease versus nodules over 3 mm, irregular, typical of chronic viral hepatitis and autoimmune disease.

### Which cell produces cirrhotic fibrosis?

Activated stellate cells (Ito cells) transdifferentiated into myofibroblasts depositing type I collagen in the space of Disse.

### What are the two mechanistic groups of cirrhotic complications?

Portal-hypertensive complications (variceal bleeding, splenomegaly, ascites) and hepatocellular failure complications (coagulopathy, encephalopathy, hypoalbuminaemia).

### How is hepatocellular carcinoma surveillance performed in cirrhosis?

Six-monthly abdominal ultrasound with or without alpha-fetoprotein, per current guidance, since cirrhosis is the strongest risk factor.
