Primary adenocarcinoma of the appendix of the true colonic type is an extremely rare tumor involving an organ that is commonly removed surgically.6 In a series reported by Collins4 of 50,000 appendices removed surgically or examined at autopsy, only 41 primary adenocarcinomas of the appendix were found. This represents 0.082% of the total number, or a frequency of 1 in every 1200 appendices. These rare tumors, usually undiagnosed preoperatively, suddenly confront the surgeon during the course of an operation for some other condition. Consequently, the recognition of the true nature of the tumor and the selection of an appropriate procedure may tax the most educated and experienced surgeons.
