Amniotic cells in fetal Fallopian tubes.
In a dizygotic 25-week-old twin fetus the histologic examination of the Fallopian tubes disclosed an unusual finding: the bilateral salpingeal lumen was filled with amniotic cells. The latter were especially numerous in the ampulla which still had few folds and which therefore had a comparatively wide  lumen. Amniotic cells and numerous granulocytes were present in stomach and duodenum, but no focus of perforation could be demonstrated. The clinical significance of the so far unknown resorptive potential of the Fallopian tubes and the possible late complications of prenatal intraperitoneal blood transfusions are discussed.
