title: Scanning electron microscopy of human Fallopian tube in ectopic pregnancy.
abstract: The scanning electron microscopy by virtue of its high resolution topographic reproduction of epithelial surfaces lining the female genital tract, provides unique information toward understanding the anatomy and physiology of the female reproductive system. The human Fallopian ectopic pregnancy is an urgent gynecologic event, which was and still is a diagnostic challenge. There is an increase in the incidence of ectopic pregnancy in recent years. With the purpose of exploring the etiology of tubal ectopic pregnancy from the ultrastructure point of view, we examined 7 cases of tubal pregnancy and compared them to a similar number of normal tubes. We do not find evidence to the pathophysiology of tubal pregnancy by examination of the ultrastructure of the human tube with scanning electron microscopy.
