Though nonfatal, leprosy is one of the most common causes of nontraumatic peripheral neuropathy worldwide.Why leprosy does not affect central nervous system?
Leprosy bacilli are unable to penetrate directly into the nervous system proximal to the dorsal root ganglions; central nervous system infection does not occur.What is the differential diagnosis for leprosy?
Among the cutaneous infectious granulomas that may be considered in the differential diagnosis of leprosy are tuberculosis (lupus vulgaris, tuberculosis verrucosa cutis, erythema induratum of Bazin), “lepromatoid” atypical mycobacterial infection (e.g., mycobacterium chelonae), leishmaniasis skin infections (lupoid, ...Is leprosy genetically transmitted?
Leprosy is not inherited, but people can inherit an increased risk of contracting leprosy if they are exposed to the Mycobacterium leprae bacteria. Susceptibility tends to run in families, but the inheritance pattern is unknown.Is Eczema a form of leprosy?
