Cutaneous and mediastinal lymphadenitis due to Mycobacterium kansasii.

Mycobacterium kansasii most commonly causes a slowly progressive pulmonary disease. Skin and disseminated infections are seen less frequently and only in immunocompromised hosts. To our knowledge, no case of Mycobacterium kansasii infection or skin infection associated with additional organ involvement in an immunocompetent patient has been reported.
