title: [Fever, malaise and new onset mitral valve insufficiency. Subacute Streptococcus bovis mitral valve endocarditis ].
abstract: A 62-year-old patient with low grade fever, fatigue, arthralgia and newly discovered mitral regurgitation was diagnosed with subacute endocarditis. Streptococcus bovis grew from all six blood culture bottles. Streptococcus bovis is known to be associated with gastrointestinal neoplasias. Therefore a colonoscopy was performed and two polyps were removed. Histological analysis revealed a tubulovillous adenoma and a serrated adenoma. Colonoscopy is mandatory for all patients with Streptococcus bovis endocarditis even without any symptoms for colorectal neoplasia. The significance of Streptococcus bovis for the carcinogenesis of colorectal neoplasias and the possible alternative pathway for colorectal carcinomas through serrated adenomas will be discussed.
