Villous adenoma of the appendix: report of a case and review of the literature.

This report presents a case of a 23-year-old white woman who presented with symptoms of acute appendicitis, confirmed at laparotomy. The appendectomy specimen revealed an isolated, noninvasive villous adenoma of the appendix. Appendectomy was judged to be sufficient treatment in this case since the base of the organ was not involved, and there was no submucosal spread of the villous adenoma. Literature on the subject is reviewed, and modalities of surgical treatment of "invasive" villous adenoma of the appendix are discussed.
