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

We present a case of Streptococcus gallolyticus 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 S. gallolyticus infection. We believe that clinicians should be aware of this association as it demonstrates how to perform gastroenterological follow-up for patients infected with S. gallolyticus, particularly those with poorly controlled DM.
