[Eggs of Enterobius vermicularis in vaginal smears]

The technique of exfoliative cytology is used especially for early cancer diagnosis with cervical and vaginal smears. In these smears, some parasites eggs can be seen together with some kind of cells. One of these parasites is Enterobius vermicularis. Normally, this is intestinal parasite. But sometimes, especially in children, this parasite eggs can migrate in vagina by itching, and can cause vaginal discharge. The shape of egg is, one border is flat but the other is convex, and it may contain larva inside. We also observed the egg of Enterobius vermicularis which contains larva inside with squamous epithelial cells and polymorphonuclear leucocytes in a vaginal smear. As is seen, routine Papanicolaou smears are very useful to see unusual eggs of parasites during cancer detection.
