A 67-year-old man clinically diagnosed a year earlier with sarcoidosis based on low-grade fever, lymphadenopathy, trunk skin rash, and histopathological skin tests was admitted for newly developing subcutaneous nodules on the trunk and arms and fever of 38℃. Although initially suspected of recurrent sarcoidosis,he was diagnosed with Mycobacterium chromogenicum infection isolated from skinl esion culture.Combined clarithromycin of 800 mg/day, ethambutol of 750mg/day, and embiomycin of 0.5g/day was started, after which fever declined and WBC count and CRP decreased to normal in a week. One month later, skin lesions had disappeared. This case is interesting considering the association of nontuberculous mycobacterial infection with sarcoidosis.
