Enterococcus faecalis Infective Endocarditis Associated With Colorectal Cancer.

Enterococcus faecalis (E. faecalis) is considered the third most common source of infective endocarditis. Some of the published reports linked its origin to colorectal cancer. We report a 70-year-old male patient diagnosed with E. faecalis infective endocarditis complicated by myocardial infarction. The patient also experienced symptoms of melena and anemia, prompting a colonoscopy. A colon mass was found and a biopsy revealed adenocarcinoma. The patient underwent a left hemicolectomy. In addition to that, he was treated for his cardiac issues. Many studies suggest screening for colonoscopy in patients with E. faecalis infective endocarditis to investigate its origin and potential association with colorectal cancer.
