Summary
This review details pemphigus, a blistering disease, focusing on its classification, pathogenesis, and treatment. It highlights histopathological features differentiating subtypes and identifies HLA phenotype and glycocalyx changes as key to its development.
Area of Science:
- Dermatology
- Immunology
- Pathology
Context:
- Pemphigus is a group of autoimmune blistering diseases.
- Understanding its pathogenesis is crucial for effective management.
- Distinguishing pemphigus from other vesiculobullous dermatoses is clinically important.
Purpose:
- To provide a comprehensive overview of pemphigus.
- To elucidate the histopathological features that classify and differentiate pemphigus variants.
- To review the pathogenesis, clinical presentation, and treatment strategies.
Summary:
- Pemphigus classification relies on histopathological similarities of intraepithelial lesions and histotopographical differences.
- Key pathogenetic factors include specific HLA phenotypes and autoantigenic denaturation of the glycocalyx.
- The review covers clinical features, differentiation from other blistering conditions, oral pemphigus manifestations, and treatment principles.
Impact:
- This review aids clinicians in accurate diagnosis and appropriate treatment selection for pemphigus.
- It enhances understanding of the autoimmune mechanisms underlying pemphigus.
- Provides a foundation for further research into novel therapeutic targets.
