Carcinoma of the colon 2 years after endocarditis due to Streptococcus bovis.

A patient with Streptococcus bovis endocarditis, on complete gastrointestinal evaluation had only an adenomatous polyp of the sigmoid colon. Twenty-eight months later she was found to have invasive cecal carcinoma. Periodic evaluation of the gastrointestinal tract is therefore recommended for all patients with a history of S. bovis septicemia.
