면역 저하 환자에서 발생한 파종성 Mycobacterium intracellulare 감염 1예

We report a case of disseminated Mycobacterium intracellulare infection in a 31-year-old man who had been diagnosed as having dermatomyositis and systemic lupus erythematosus 3-years prior. The patient developed a left pleural effusion M. intracellulare was repeatedly isolated from the pleural fluid. After antimycobacterial treatment, the patient's pleural effusion resolved, but a left knee joint effusion developed newly and M. intracellulare was cultured from the joint fluid. At present, the patient has been taking antimycobacterial medication for 15 months but his left knee joint fluid remains positive for M. intracellulare. To our knowledge, this is the second reported case of disseminated NTM infection in a non-HIV infected patient in Korea. 본 증례는 AIDS가 아닌 면역저하 환자에서 M. intracellulare에 의하여 관절염 및 흉수가 발생한 파종성 질환의 예로 국내에서 두 번째로 보고되는 바이다.
