HYPERPLASTIC COLONIC POLYPS - AN INHOMOGE NEOUS GROUP OF PATHOLOGICALAND ANATOMICAL CHANGES

A total of 334 hyperplastic polyps of the colon of 266 patients were e xamined under epidemiologically, morphometrically and histochemically. Of these, 62 cases (23%) were associated with adenomas, 18 cases (7%) with carcinomas. Hyperplastic polyps are not entirely homogeneous, pa thologically and -anatomically: Carcinoma-associated hyperplastic poly ps are larger in diameter,the size and width of their crypts is greate r, and they have a higher percentage of goblet cells with a higher amo unt of sialomucins as shown by HID/AB stain.
