A total of 17 cases of infective endocarditis due to M luteus have been reported in the literature to date all involving prosthetic valves. To the best of our knowledge we describe the first case of native aortic valve M luteus endocarditis in an immunosuppressed patient in this report. Case report A 74-year-old Greek-Cypriot woman was admitted to our Internal Medicine Clinic due to fever and malaise and the diagnosis of aortic valve M luteus endocarditis was made. She was immunosuppressed due to methotrexate and steroid treatment. Our patient was unsuccessfully treated with vancomycin gentamicin and rifampicin for four weeks. The aortic valve was replaced and she was discharged in good condition. Conclusions Prosthetic infective endocarditis due to M luteus is rare. To the best of our knowledge we report the first case in the literature involving a native valve.
