It was first recognized by Hansen in 1873 in Bergen, Norway, while examining smears from lepromas of Norwegian patients. Notably, the organism was the first reported bacterium causing chronic disease in humans that principally affects the cooler parts of the body, especially the skin, upper respiratory tract, testes, eyes, and superficial segments of peripheral nerves.1,2 The stigma suffered by patients with leprosy has historically been severe. For a review of the history of leprosy refer to the electronic text. Because of the stigma of leprosy, the physician must carefully consider the social implications of a diagnosis of leprosy, especially in children.
