Villous adenoma presenting as a vaginal polyp in a rectovaginal tract.
A 72-year-old woman had a villous adenoma of endodermal derivation involving the rectovaginal septum and contiguous mucosal surfaces that presented clinically as a vaginal polypoid tumor. To explain the vaginal involvement, we postulate that the adenoma traversed a tract of developmental origin within the rectovaginal septum. This is the first report of such a unique constellation of findings.
