Favorites Abstract PIP: Regarding maternal ingestion of stilbestrol to high-risk pregnant patients during the late 's and early 's and the appearance of vaginal adenocarcinoma in their female offspring years later, physicians are advised to examine patients whose mothers received stilbestrol during pregnancy.
