Pinworm is a cosmopolitan parasite with particularly high prevalence in countries with a temperate climate. A significant decrease between the Enterobius vermicularis positive patients and the control group was detected in the level of ADA (p=0.0001). In female the nematode migrates up the uterus and fallopian tubes to produce a foreign-body type of granulomatous inflammation most commonly seen in the surface of the ovaries, omentum, and peritoneum. The patient was a 23-year-old Malaysian woman who presented with suprapubic pain and vaginal bleeding. Negative findings for Enterobius are recorded from ten postmortem examinations and fourteen NIH swab examinations of Rhesus Monkeys(Macaca mulata).

Enterobius vermicularis infection of female genital tract: a report of three cases and review of literature.

Enterobius vermicularis (the pinworm) commonly infests the lumen of the intestine but on rare occasions has been found in the wall or in the tissues outside the gastrointestinal tract. The females are considerably larger than the males, measuring 8 to 13 mm long and have a tapering posterior end that ends in a long filamentous tail. The ova are occasionally found in ectopic sites within the peritoneal cavity, usually as an asymptomatic granuloma.
Methods: Eighty children (45 boy, 35 girl, age range 4-7 years) participated in this study. vermicularis, 69% had no evidence of appendicitis and of those that had, no gangrene or perforation was seen.
