Streptococcus gallolyticus Infection Associated With Colorectal Adenoma in a Patient With Type 1 Diabetes Mellitus: A Case Report

We present a case of <i>Streptococcus gallolyticus</i> sepsis in a patient with type 1 diabetes mellitus (T1DM) who had poor glycemic control. Once the sepsis and infection had improved, we examined the patient for colorectal adenoma or carcinoma and detected a stalked polyp with colonoscopy. Therefore, this case underscores the importance of actively screening for malignant colonic diseases in patients with <i>S. gallolyticus</i> infection. We believe that clinicians should be aware of this association as it demonstrates how to perform gastroenterological follow-up for patients infected with <i>S. gallolyticus</i>, particularly those with poorly controlled DM.
