## Direct answer

Liver pathology pivots on viral hepatitis, alcohol and fatty liver disease progressing to cirrhosis, whose complications — portal hypertension with varices, ascites, spontaneous bacterial peritonitis, encephalopathy and hepatocellular carcinoma — dominate practice. Metabolic disease carries exam markers: haemochromatosis with bronze diabetes, Wilson disease with Kayser-Fleischer rings and low caeruloplasmin. Biliary pathology adds gallstones, primary biliary cholangitis with antimitochondrial antibody, primary sclerosing cholangitis with ulcerative colitis, and the special hepatitis E danger to pregnant women in India.

## What you must remember

- Viral hepatitis: A and E spread faeco-orally in waterborne outbreaks, hepatitis E carrying high mortality in pregnancy; B, C and D spread parenterally and vertically — hepatitis B shows ground-glass hepatocytes and drives cirrhosis and cancer, while C chronifies in most and is a leading cirrhosis cause.- Alcoholic liver disease: reversible fatty liver to alcoholic hepatitis with Mallory bodies, neutrophils and AST more than double ALT, to micronodular cirrhosis. Non-alcoholic fatty liver disease tracks metabolic syndrome and is the commonest chronic liver disease in most series.
- Cirrhosis complications: variceal bleeding, congestive splenomegaly with pancytopenia, ascites with spontaneous bacterial peritonitis (neutrophils above 250 per microlitre), lactulose-responsive encephalopathy with asterixis, hepatorenal syndrome and vitamin K-resistant coagulopathy.
- Haemochromatosis: HFE C282Y autosomal recessive iron overload — bronze diabetes, cirrhosis with raised cancer risk, cardiomyopathy, metacarpophalangeal arthropathy, high ferritin and transferrin saturation.
- Wilson disease: ATP7B copper transporter failure with low caeruloplasmin, Kayser-Fleischer rings, basal ganglia disease and Coombs-negative haemolysis in acute liver failure.
- Vascular and infective: Budd-Chiari hepatic vein thrombosis with painful hepatomegaly and ascites; amoebic liver abscess with anchovy-paste aspirate, common in India; hydatid cyst with daughter cysts and anaphylaxis on spillage.
- Gallbladder and ducts: cholesterol stones in fat, fertile, forty-plus females; pigment stones with haemolysis; porcelain gallbladder and carcinoma; Charcot triad of cholangitis. Primary biliary cholangitis — middle-aged women, antimitochondrial antibody, pruritus with high alkaline phosphatase; primary sclerosing cholangitis — young men with colitis, beaded ducts.
- Hepatocellular carcinoma arises in cirrhosis of any cause and with hepatitis B; six-monthly ultrasound and AFP surveillance in cirrhotics; fibrolamellar variant in the young without cirrhosis fares better; metastases are the commonest liver tumours.

## Common confusion

Primary biliary cholangitis versus primary sclerosing cholangitis: middle-aged woman with antimitochondral antibody and small-duct destruction against young man with ulcerative colitis and beaded ducts. Alcoholic hepatitis is read from the AST-ALT ratio above two and Mallory bodies. In jaundice syndromes, Gilbert is mild and benign, Crigler-Najjar severe with kernicterus risk, Dubin-Johnson conjugated with a black liver.

## Exam-focused takeaway

FMGE quotes classic phrases — ground-glass hepatocytes, nutmeg liver, anchovy-paste abscess, Mallory bodies — and asks for the marker: ferritin for haemochromatosis, caeruloplasmin for Wilson, AFP for hepatocellular carcinoma, antimitochondrial antibody for primary biliary cholangitis. Complication stems cover variceal bleeding, peritonitis thresholds and encephalopathy care. Hepatitis E in pregnancy is a near-regular Indian question.

## Frequently asked questions

### Which hepatitis virus endangers pregnancy?
Hepatitis E, waterborne, causing fulminant failure with substantial third-trimester maternal mortality. Safe water and sanitation prevent it.
### What are Mallory bodies?
Eosinophilic tangled cytokeratin filaments in hepatocytes, characteristic of alcoholic hepatitis alongside neutrophils and steatosis; an AST more than twice ALT supports the diagnosis.

### How does haemochromatosis present?
Bronze pigmentation with diabetes, fatigue, metacarpophalangeal arthropathy, cardiomyopathy and cirrhosis; venesection is the treatment.

### What confirms Wilson disease?
Low caeruloplasmin, high urinary copper, Kayser-Fleischer rings and raised hepatic copper; ATP7B testing helps unclear cases. Chelation is lifelong.

### What is Budd-Chiari syndrome?
Hepatic venous outflow obstruction from thrombosis in hypercoagulable states, presenting with abdominal pain, ascites and hepatomegaly; anticoagulation or a shunt may be needed.

### Which tests form hepatocellular carcinoma surveillance?
Ultrasound with serum alpha-fetoprotein at six-monthly intervals in cirrhotic patients. Multiphase imaging characterises any nodule found.
