Below are microscopic findings obtained from liver biopsies of various adult patients presenting with elevated liver enzymes or cholestatic markers. Match each histopathological description with the most appropriate disease process.

  • Hepatocyte ballooning, macrovesicular steatosis, Mallory-Denk bodies, and prominent neutrophilic infiltrateAlcoholic hepatitis
  • Florid duct lesions with noncaseating granulomatous destruction of small intrahepatic bile ductsPrimary biliary cholangitis
  • Concentric periductal 'onion skin' fibrosis causing obliteration of medium and large extrahepatic and intrahepatic bile ductsPrimary sclerosing cholangitis
  • Intense portal lymphoplasmacytic infiltrate with interface hepatitis, extending into the hepatic lobuleAutoimmune hepatitis

Cevap

The accurate matches are: Hepatocyte ballooning/neutrophils with Alcoholic hepatitis; Florid duct lesions/granulomas with Primary biliary cholangitis; Concentric 'onion skin' fibrosis with Primary sclerosing cholangitis; and Lymphoplasmacytic infiltrate with Autoimmune hepatitis.
Each hepatobiliary disease possesses a signature histologic pattern on liver biopsy that reflects its distinct underlying pathophysiology. Recognizing these specific cellular infiltrates and architectural changes is critical for establishing a definitive diagnosis and guiding appropriate targeted therapy.

Adım Adım Çözüm

1
Analyze the first histopathologic description focusing on Mallory-Denk bodies and a neutrophilic infiltrate.
Matched to alcoholic hepatitis.
Alcoholic liver disease uniquely features neutrophil-predominant inflammation and cytoskeletal damage (Mallory-Denk bodies) rather than a primarily lymphocytic response.
2
Evaluate the second description highlighting florid duct lesions and granulomas.
Matched to primary biliary cholangitis.
PBC is an autoimmune process causing granulomatous destruction of small, intrahepatic bile ducts.
3
Assess the third description noting concentric 'onion skin' periductal fibrosis.
Matched to primary sclerosing cholangitis.
PSC is characterized by fibro-obliterative inflammation of medium and large bile ducts, creating a classic 'onion skin' appearance.
4
Review the fourth description detailing a lymphoplasmacytic infiltrate with interface hepatitis.
Matched to autoimmune hepatitis.
Autoimmune hepatitis presents with plasma cell-rich inflammation attacking the hepatocyte junction (limiting plate).
