Abstract

Backgound Lepra reactions are a chronic debilitating public health problem. It causes nerve damage, loss of limbs and deformities. They may occur during the natural course of the disease, throughout treatment or after it. Wide variations in clinical presentation make histopathology an important tool. There needs to be more inclusive histologic criteria for diagnosing lepra reactions.

 

Objective This study aims to analyse clinical diagnosis with histopathological findings, different histological types of lepra reactions and their changes, and the frequency of mycobacterial positive cases in lepra reaction cases using Modified Fite’s stain.

 

Methods The clinically suspected cases of lepra reactions, irrespective of age and sex attending OPD in Department of Dermatology, at North Bengal Medical College and Hospital were biopsied.

 

Results Histopathological features based on the type of infiltrate predominance of neutrophilic infiltration, vasculitis, and supporting features like vasculitis, neutrophilic abscess formation within the dermis will help in clinching a diagnosis of ENL, while a predominant lymphocytic infiltrate, intra granuloma oedema along with presence of giant cells and oedema of papillary dermis will be commoner in T1LR.

 

Conclusion Histopathology along with clinical findings will help in proper identification of atypical cases.
