title: Recurrent Mycobacterium xenopi infection in a patient with rheumatoid arthritis receiving etanercept.
abstract: A case of recurrent Mycobacterium xenopi infection presenting as Pott's disease in a patient receiving etanercept for severe rheumatoid arthritis is described. A 49-y-old Caucasian male had received a total of 11 months of anti-mycobacterial therapy for hip infection acquired 15 months earlier; he presented with progressive back pain, which was diagnosed as Pott's disease. He had been treated with etanercept in addition to his prior immunosuppressive agents after the diagnosis of hip infection.
