Summary
Histopathological examination is crucial for accurate leprosy subtyping. This study found higher concordance between clinical and histopathological diagnoses using the World Health Organization (WHO) classification, aiding precise treatment.
Area of Science:
- Dermatology
- Pathology
- Infectious Diseases
Background:
- Leprosy diagnosis relies on clinical presentation and classification systems.
- Accurate subtyping is essential for effective treatment and patient management.
Purpose of the Study:
- To evaluate the clinico-histopathological correlation in leprosy patients.
- To compare the concordance rates of Ridley-Jopling (R-J) and World Health Organization (WHO) classifications.
Main Methods:
- Histopathological examination of skin biopsies from 111 leprosy patients.
- Staining with Hematoxylin and Eosin (H&E) and Ziehl-Neelsen (Z-N) stains.
- Classification using R-J and WHO criteria, with statistical analysis including the kappa test.
Main Results:
- Leprosy evidence found in 93.69% of skin biopsies.
- Overall concordance: 58.6% (R-J) and 85.6% (WHO).
- WHO classification showed higher concordance rates for individual and combined subtypes.
Conclusions:
- Histopathological examination is vital for precise leprosy subtyping.
- The WHO classification demonstrates superior agreement with histopathology.
- Accurate subtyping facilitates appropriate therapy and patient follow-up, preventing complications.
