Sarcoidosis is a multisystemic disorder characterized by the presence of non-caseating granulomas in the involved organ. Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis and is characterized by granuloma with caseous necrosis. The clinical and histological similarity between sarcoidosis and tuberculosis has stimulated research searching for an association between mycobacterium and sarcoidosis. We report a case of a 38-year-old male with sarcoidosis that developed soon after treatment of tuberculous lymphadenitis. He was diagnosed as tuberculous lymphadenitis by microbiological confirmation. He showed clinical improvement after treatment for tuberculosis. One year later, his chest radiography showed bilateral hilar enlargement with diffuse bilateral nodules. A noncaseating granuloma was confirmed by endobronchial ultrasound guided transbronchial needle aspiration and he was diagnosed with sarcoidosis. To our knowledge, this is the first report describing sarcoidosis after treatment of tuberculosis in South Korea.
