Case for diagnosis

Hansen's disease is a chronic infecto-contagious disease caused by mycobacterium leprae. the bacillus prefers low-temperature areas and the nose is usually the initial site of lesions. transmission of the bacilli occurs by nasal and oropharyngeal secretions,and through solutions of continuity of the skin and/or mucosae. nasal manifestations are found in the later stages of the disease. © 2014 by anais brasileiros de dermatologia.
