Left: 44 year-old woman undergoing colonoscopy for evaluation of occult bleeding had several similar polyps on stalks. Although the head of this polyp was erythematous and inflammatory in appearance, it was histologically found to be a true adenoma.
Center: 77 year-old woman was found to have this smooth bi-lobed polyp on a stalk; the lesion proved to be a tubular adenoma.
Right: 66 year-old woman with gastrointestinal bleeding. This erythematous polyp on a broad stalk proved to be
a tubular adenoma.
Left & Center: Unusually long stalk, several times larger than the polyp itself (head of small tubular adenoma visible in image on left), in a 77 year-old man with hematochezia.
Right: Benign tubular adenoma on a long stalk in the colon of a 41 year-old woman with hematochezia.
Left: 52 year old woman undergoing colonoscopy for average risk colon screening. This 1.5 cm pedunculated polyp was excised from the
