Abstract
A case of noninvasive villous adenoma of the appendix in a 62-year-old man with 26 months of follow-up is reported. Of the known 37 patients with noninvasive appendiceal villous adenoma, 19 had symptoms referable to the appendix and acute appendicitis microscopically. The other 18 lesions were found in incidental appendectomies. There was generalized mucosal involvement of the appendix in seven patients. The lesion extended to the resection line in four, but was not found in the cecum of the three who underwent partial cecectomy or right hemicolectomy. Appendectomy is adequate for noninvasive villous adenoma that does not reach the resection line. For those cases attaining the resection line, cecectomy is advisable, but right hemicolectomy appears to be too aggressive for a noninvasive lesion.
