This article deals with medical liver disease. An introduction to the liver and approach is found in the liver article.
Every differential in liver pathology has "drugs"[1] -- if it isn't clearly malignancy.
Liver neoplasms are dealt with in the liver neoplasms article.
Medical liver biopsies are often non-specific, as the liver has the same appearance for many mechanisms of injury, especially when the injury is marked. The clinical history, serology and imaging are essential for proper interpretations in this domain of pathology.
Review of liver blood work
Inflammation activity
- ALT.
- AST.
Cholestatic markers
- ALP.
- GGT - used to assess whether the ALP is an "honest" value, elevated in cirrhosis.
Cirrhosis/decompensation
- PLT - low is suggestive of dysfunction.
- INR - high is bad, unless anticoagulated.
Other
- Bilirubin.
- Direct (AKA conjugated).
- Indirect (AKA unconjugated).
A short DDx of elevated:[2]
- Indirect:
- Gilbert syndrome.
- Crigler-Najjar syndrome type 1.
- Crigler-Najjar syndrome type 2.
- Direct:
- Rotor syndrome.
- Dubin-Johnson syndomre.
Viral hepatitis
- HBV DNA.
- HCV RNA.
- HBs Ag, HBs Ab, HBe Ag, HBe Ab.
- HCV Ab.
Others:
- Epstein-Barr virus (EBV).
- Cytomegalovirus (CMV) - especially in the immune incompetent.
Hepatitis B
Meaning & utility of the various Hepatitis B tests:[3][4]
Test name | Location | Positive test | Negative test | Usual question |
---|---|---|---|---|
HBs Ag | Surface | Virus active | No active infection | Active infection? |
HBs Ab | Surface | Exposed OR vaccinated | No exposure OR no vaccine OR loss of Ab | Immunization status? |
HBe Ag | Virus core | Infect. w/ viral replication | No active infection | Active infect. w/ viral replication? |
HBe Ab | Virus core | Exposed to virus | Infect. w/o antibody response OR not exposed | Immune response to infection? |
HBV DNA | - | Active | Not active/no exposure | Viral load/how active? |
HBc Ab | Virus core | Virus active/previous exposure | No exposure | Early active infection? |
Notes:
- HBc Ab may test for acute (IgM) or chronic infection - dependent on specific antibody test; it is often used to look for early infection.[4]
- Carriers of hepatitis B: HBs Ag +ve, HBs Ab -ve, HBc Ag -ve, HBc Ab +ve, HBe Ag -ve, HBe Ab +ve.[5]
Markers for rare liver diseases
- Ceruloplasm - low think Wilson's disease; typical value for Wilson's ~ 0.12 g/L.
- <0.20 g/L is a criteria for Wilson's disease.[6]
- Alpha-1 antitrypsin - if low think deficiency.
Hemosiderosis
- Ferritin - high.
- Iron saturation - high.
Causes:
- Hemochromatosis.
- Hemolysis, chronic.
- Cirrhosis.
Medical imaging
Blood flow:[7]
- Hepatopedal flow = normal portal vein flow.
- Hepatofugal flow = reversed portal vein flow.
Interventional measurements
Wedged to free hepatic venous pressure:[8]
- Normal = 1-4 mmHg.
- Elevated in portal hypertension.
Liver biopsy
Medical liver biopsy adequacy
Liver biopsy specimens should be:[9]
- 2.0 cm in length and contain 11-15 portal tracts,
- The core should be deeper than 1.0 cm from the liver capsule; specimens close to the capsule may lead to over grading of fibrosis.
Reporting
Specimen, procedure: - Diagnosis.
The diagnosis usually contains grading and staging information, e.g. activity 2 /4, Laennec fibrosis stage 1 /4.
In the context of medical liver disease:
- Grade = inflammation/activity.
- Stage = severity of fibrosis/architectural changes.
Notes:
- The term "acute" is infrequently used in liver pathology.
- In the liver: neutrophils is not acute -- unlike most elsewhere in the body.[10]
A microscopic checklist
Size of biopsy: Adequate Fragmentation: Absent Fibrosis: Stage 2-3/4, mostly stage 2 Fibrous septa: Present Septa with curved contours: Present – focally only Large droplet steatosis (% of hepatocytes): Present, moderate 60% Ballooning of hepatocytes: Present, rare Mallory-Denk bodies: Present, rare Portal inflammation: Present Interface activity: Minimal (0-1/4) Lobular necroinflammation: Minimal Ducts: Present in normal numbers Duct injury: Absent Ductular reaction: Absent Cholestasis: Absent Terminal hepatic venules: Present Iron stain: Absent Ground glass cells with routine stains: Absent PASD for alpha-1 antitrypsin droplets: Negative
Viral hepatitis
These are common. The diagnoses are based on serology. The serology is covered in the viral hepatitis section in the liver pathology article.
Typically classified as:[11][12]
- Acute < 6 months duration.
- Chronic > 6 months duration.
Hepatitis A
- Infection is self-limited, i.e. not persistent.
- May present as fulminant hepatic necrosis.
- Usually asymptomatic in children.[13]
- Serology is diagnostic.
Hepatitis B
- Hepatitis B virus, abbreviated HBV, redirects here.
Hepatitis C
General
- Leads to hepatocellular carcinoma in the setting of cirrhosis.
- Tends to be chronic; the "C" in "hepatitis C" stands for chronic.
- Diagnosis is by serology.
Associated pathology:
Microscopic
Features:
- Lobular inflammation - this is non-specific finding.
- Usually Grade 1, rarely Grade 2 and almost never Grade 3 or Grade 4.[14]
- Periportal steatosis in genotype 3.[15]
- Steatosis in hepatitis C is usually a secondary pathology, i.e. a separate pathologic process.[16]

Metavir activity index 1 (Piecemeal necrosis 0-1, Lobular necrosis 1), Metavir fibrosis stage 2. Hepatitis C genotype 1a. Expanded, dark triads (UL blue arrowhead). Focus of spotty necrosis (UR green arrowhead). Reticulin shows occasional, equivocal foci of piecemeal necrosis, with a thin black line possibly encircling a hepatocytes (LL yellow arrowhead); the activity index is unaffected by the difference in piecemeal necrosis score. Trichrome shows portal fibrosis with extension outside area of blood vessels (LR purple arrowhead) Original oculars UL 2X, UR 20X, LL 40X, LR 40X | |
Metavir activity index 2 (Piecemeal necrosis 2, Lobular necrosis 1). Hepatitis C genotype 3a. Steatosis, not pan-acinar and dark, expanded triads(UL) with the inset showing a Councilman body. Reticulin collapse, not portal-central (UR green arrowhead). Reticulin with more than focal piecemeal necrosis in some triads/tracts (LL magenta arrowheads) Trichrome stain of a tract (the entire structure may be a large bridge) with thinner bridges (LR cyan arrowheads).
Original oculars. UL 4X (inset 40X with higher magnification), UR 20X, LL 40X, LR 10X | |
Metavir activity index 3 (Piecemeal necrosis 2, Lobular necrosis 2), Metavir fibrosis stage 4. Hepatitis C genotype 1a. Inflamed bands separate hepatocyte regions distorted by steatosis (UL). Bordering tract and acini (UR) lymphocytes, macrophages, eosinophils, and rare neutrophils (black arrowhead) invest both proliferated bile ducts (yellow arrowheads) and hepatocytes, some showing ballooning degeneration (green arrowhead). Reticulin shows hepatocyte cords often two nuclei thick bounded by directionless sinusoids, consistent with a regenerative nodule (LL). Trichrome shows extensive bridging with a potential flattened nodule; although a debate about the presence or absence of definite fibrosis would have existed, with the Metavir scoring system, this is considered fibrosis stage 4 (LR).
