P. Koirala Institute of Health Sciences, Dharan, Sunsari, Nepal Leprosy is a chronic bacterial disease caused by Mycobacterium leprae. It is the oldest known disease to human beings. Incubation period ranges from weeks to years. The prevalence of leprosy varies markedly from country to country. However, the overwhelming majority of cases are found in developing countries and 92 percent of the cases are detected in just 11 countries led by India and Brazil. Grossly leprosy is divided into lepromatous and tubercular form, based on immunological pattern of disease. Though leprosy is common condition, isolated leprosy of pinna has not been reported so far in the literature.
