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.
增生性息肉是结直肠息肉最常见的类型。它们通常为多发，局限于直肠乙状结肠区域。其体积小（<10mm）、无蒂、表面光滑且半透明，易于识别。通常，这些息肉无恶变潜能。我们报告一例68岁男性病例，该患者有多个直肠乙状结肠息肉，其中一些具有腺瘤性息肉的宏观特征。由于在检查时对两个对应的腺瘤性息肉进行内镜下息肉切除术后出现出血，且这些息肉多发并位于憩室病部位，遂行左半结肠切除术及结肠肛管吻合术。手术标本的组织学检查显示所有息肉均为增生性，其中两个有腺瘤组织灶。
