title: [Giant hyperplastic polyposis with adenomatous tissue].
abstract: Hyperplastic polyps are the most common type of colorectal polyps. They are usually multiple and localized in the rectosigmoid area. They are easily recognized by their small size (< 10 mm), sessile form, smooth-surface and translucid appearance. Typically, these polyps have no malignant potential. We report the case of a 68-year-old man who had multiple rectosigmoid polyps, some of them having macroscopic features of adenomatous polyps. Because of the occurrence of bleeding after endoscopic polypectomy of two polyps corresponding to adenomas at examination, because of the multiplicity of these polyps and their localization in diverticulosis, a left colectomy followed by coloanal anastomosis was performed. Histologic examination of the surgical specimen revealed the hyperplastic nature of all polyps with, in two of them, a focus of adenomatous tissue.
