Mycobacterium leprae have the affinity for peripheral nerves and neuropathy is a cardinal manifestation of the disease. The nerve damage affects sensory, motor, and autonomic fibers resulting in the physical impairments and limitation of physical activities and social participation. Leprosy is a curable disease and treatment provided in the early stages will avert the disabilities. Approach to the neuritic leprosy depends on its clinical characteristics, nerve biopsy, and histological appearance of dermatological and neurological lesions.
