Single lesion lepromatous leprosy in a teenager: an unexpected scenario

Hansen’s disease (HD) is a chronic granulomatous disease principally affecting the skin and peripheral nervous system caused by Mycobacterium leprae. The incubation period varies from months to more than 30 years. The tuberculoid form of HD usually presents with a single hypoesthetic patch and skin biopsy shows epithelioid granulomas with absence of bacilli on Fite-Faraco stain. In contradistinction, lepromatous leprosy usually presents with numerous papules, plaques and nodules with induration of the ears and nose. Biopsy shows foamy granulomas with presence of acid-fast bacilli on Fite-Faraco stain.
