Background: In the last decade, body piercing has gained strongly in popularity. There are a few reports in the literature regarding infective endocarditis after body piercing.
Case Report: The case of an 18-year-old girl with heart failure and a six-month history of recurring fever is presented. Clinical and laboratory evaluation led to the diagnose of infective endocarditis due to Gemella morbillorum. Oral piercing was recognized to be the cause of bacteremia. Fourteen cases of infective endocarditis related to body piercing were found in the literature and the clinical, etiologic, pathogenic, and preventive aspects of this topic are presented.
Conclusions: Infective endocarditis may be a complication of body piercing and has been observed in patients with heart lesions as well as in previous healthy people. Infective endocarditis can follow body piercing involving either mucous membranes or the skin. This patient is the first case of Gemella morbillorum endocarditis after body piercing reported in the literature. Careful observation for infection at the site of piercing and its treatment as well as professional training for operators seem to be the most effective way to minimize the risk of infective endocarditis after body piercing.
