Clinico histopathological correlation in leprosy.

Area of Science:

• Dermatology
• Infectious Diseases
• Immunology

Background:

• Leprosy is a chronic infectious disease caused by Mycobacterium leprae.
• Disease presentation varies based on host immune status, leading to diverse clinico-pathological forms.
• Clinical classification relies on lesion appearance, while histopathology offers precise, immunologically informed parameters.

Purpose of the Study:

• To evaluate the clinicopathological correlation in leprosy diagnosis.
• To assess the accuracy of histopathological classification against clinical diagnosis.

Main Methods:

• Biopsy and histopathological examination of 182 suspected leprosy cases.
• Comparison of clinical diagnoses with histopathological findings.
• Calculation of overall clinicohistological correlation and correlation for individual leprosy types.

Main Results:

• Histopathological features consistent with leprosy were found in 136 out of 182 biopsied cases (74.7%).
• Overall clinicohistological correlation was 74.7%.
• Highest correlation was observed in the LL (84.2%) and BL (73.3%) types, with lower correlations in TT (56%) and indeterminate leprosy (50%).

Conclusions:

• There is a degree of overlap in leprosy classifications, particularly in unstable forms.
• Combining clinical and histopathological features enhances diagnostic accuracy for leprosy.
• Improved diagnostic accuracy facilitates better patient management and treatment strategies.
