Primary carcinoma of the appendix

Primary adenocarcinoma of the appendix is a rare tumor. Fewer than 200 cases are on record. Correct preoperative diagnosis is virtually nonexistent. Two patients with adenocarcinoma of the appendix are described. Although appendectomy appears to be adequate treatment for carcinoid, right hemicolectomy is, in our opinion, the treatment of choice for mucinous cystadenocarcinoma, while it is mandatory in cases of adenocarcinoma of the colonic type.
