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.
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:[2][3]
- 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.[4]
- Serology is diagnostic.
Hepatitis B
- Hepatitis B virus, abbreviated HBV, redirects here.
General
- May lead to hepatocellular carcinoma without cirrhosis.
- High prevalence.
- Diagnosis is by serology.
Associated pathology:
Microscopic
Features:
- Lobular inflammation - this is non-specific finding.
- Hepatocyte necrosis:
- Necrotic hepatocytes look a lot like neutrophils - however:
- Cytoplasm is more pink.
- Round apoptotic bodies.
- Necrotic hepatocytes look a lot like neutrophils - however:
- Hepatocyte necrosis:
- Ground glass hepatocytes - see liver pathology article.

DDx:
- Hepatitis B (without ground glass hepatocytes).
- Autoimmune hepatitis.
- Primary biliary cirrhosis without granulomas.
- Drug reaction.
Other infections
- Hydatid disease (Hydatid cyst).
