Case Report: Diagnostic Pitfalls in an Atypical Case of Primary Neuritic Leprosy

Primary neuritic leprosy is a form of leprosy clinically limited to the peripheral nerves without obvious skin lesions. Diagnosing leprosy in the absence of typical dermatological features is challenging and often causes a delay in diagnosis. We describe a case of primary neuritic leprosy with atypical features and the roles that histological confirma-tion using nerve biopsy of an unenlarged nerve and newer techniques, such as polymerase chain reaction and high -resolution ultrasonography, play in improving the diagnosis.
