<bold>FIGURE 69.2</bold> Mucosal polyps of the colon may be sessile, protruding directly from the colonic wall, or pedunculated, extending from the mucosa through a fibrovascular stalk. (<i>A</i>) Large sessile polyp seen at colonoscopy. The polyp has a broad-based attachment to the mucosa. (<i>B</i>) Pedunculated polyp seen at colonoscopy. The polyp is attached to the mucosa through a distinct stalk. (<i>C</i>) Low-power photomicrograph of a pedunc...

<bold>FIGURE 69.3</bold> Histology of adenomatous polyps. (<italic>A</bold>) Tubular adenomas are characterized by a complex network of branching adenomatous glands (see also <italic>C</bold>). (<italic>B</bold>) Villous adenomas consist of glands that extend straight down from the surface to the base as fingerlike projections; this pattern may be suggested by the gross appearance of these polyps.
