There has been no reported case of appendiceal polyp in the literature in Korea. The authors experienced two cases of polyp in the vermiform appendix. The first case was a 51 year-old male patient who received a left hemicolectomy due to colonic polyposis. The second case was a 71 year-old male patient who was treated by appendectomy under the clinical diagnosis of acute appendicitis. The microscopic type of both cases were hyperplastic polyp.
