Intestinal metaplasia in stilboestrol‐induced vaginal adenosis

Abstract

We present an unusual case of vaginal adenosis with progressive intestinal metaplasia, previously undescribed, in a female patient exposed to stilboestrol in utero. Argentaffin cells were present within these areas, a feature not previously reported in benign vaginal adenosis. The development of the intestinal metaplasia coincided with the onset of a vaginal discharge so severe that, after 7 years, a vaginal resection was performed. Intestinal-type glands have been described in the cervix and ovary, almost invariably associated with malignancy. The possible role of intestinal metaplasia in the development of enteric-type neoplasms of the vagina is discussed.
