An Unusual Finding on Rectal Retroflexion

A 66-year-old male patient with hypertension and diabetes mellitus presented for a screening colonoscopy. He had no gastrointestinal complaints, namely no abdominal pain, change in bowel habits, rectal bleeding or anal itching. Colonoscopy showed diffuse diverticular disease throughout the colon. Upon retroflexion in the rectum, a 3 mm cerebriform, pale polypoid lesion was seen just proximal to the dentate line (Figure 1).
