Abstract
Summary The case report of an elderly patient who had coincidental adenocarcinomas of the sigmoid colon and of the appendix is presented. He was well for five and a half years following simple appendectomy and sigmoid resection. A new primary carcinoma of the ascending colon was then noted and removed by right hemicolectomy. The literature dealing with carcinoma of the appendix is briefly recounted. The total number of cases reported is brought to 147. While right hemicolectomy is the preferred method of managing most cases, simple appendectomy may suffice for the noninvasive form of this unusual lesion. Coincidental carcinomas of the colon and appendix are rare.
