Summary
Primary biliary cholangitis (PBC) histopathology is broader than previously thought. Recognizing diverse liver biopsy findings, including therapy-modified changes, improves diagnosis and prognosis for this autoimmune liver disease.
Area of Science:
- Hepatology
- Autoimmune Diseases
- Gastroenterology
Background:
- Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease causing bile duct injury, fibrosis, and cirrhosis.
- Diagnosis relies on biochemical markers and antimitochondrial antibodies, but liver biopsy is crucial for atypical cases and post-transplant assessment.
Purpose of the Study:
- To review the expanding histopathological spectrum of PBC.
- To highlight emerging morphological phenotypes and treatment-related changes.
- To discuss diagnostic challenges in native and transplanted livers.
Main Methods:
- Review of contemporary literature on PBC histopathology.
- Analysis of classical and emerging histopathological patterns.
- Emphasis on differential diagnosis and post-transplant findings.
Main Results:
- PBC histopathology includes classical lesions and broader phenotypes like non-destructive ductopenia and therapy-modified morphology.
- Distinct patterns are observed in native and transplanted livers, including recurrent disease.
- Accurate recognition of these varied findings is essential for diagnosis and prognosis.
Conclusions:
- The histopathological spectrum of PBC is more diverse than traditionally recognized.
- Understanding these varied patterns aids in accurate diagnosis, prognostic assessment, and managing diagnostic pitfalls.
- This review emphasizes the evolving understanding of PBC morphology in clinical practice.
