Leprosy: a ‘common’ and curable cause of peripheral neuropathy with skin lesions

Leprosy (or Hansen’s disease) is a curable chronic infectious disease caused by the acid-fast bacillus Mycobacterium leprae. While leprosy remains one of the most common causes of neuropathy worldwide, its rarity in the UK means that many doctors are unfamiliar with the typical clinical features. This is problematic because early recognition and treatment is vital in order to minimise disease-related complications such as nerve injury.
