[Morphological and stereological examinations of placenta of patient with unruptured tubal pregnancy at full term (author's transl)].

Optimum conditions for foetal life were recorded from morphological and stereological findings obtained from a patient at full-term tubal pregnancy. Basiotrophic implantation, no reduction of chorion frondosum, large placental exchange surface, and extremely good capillarisation of chorionic villi proved to be the conditions for survival of the child.
