GI Pathology II, Case 4 • 60-year-old woman with easy fatiguability and hemoglobin of 10.2 g/100ml.
A Villous Adenoma B Tubular Adenoma
Tubular Adenomas Polyp Stalk Normal adjacent colon mucosa Normal adjacent colon mucosa Even on low power note the crowded, disorganized glands of the tubular adenoma compared to the normal underlying colonic mucosa. The cells lining the glands of the polyp have hyperchromatic nuclei. There is no stalk invasion – the polyps are benign
Goblet cells Hyperchromatic nuclei The glands of the tubular adenoma are lined by goblet cells and epithelium with elongated cells containing hyperchromatic nuclei that are pseudostratified (atypical or “dysplastic” epithelium) There is no invasion of the lamina propria or submucosa.
