BACKGROUND Enterobius vermicularis in an ectopic location usually represents an incidental finding in tissue specimens in a patient without symptoms. However, the parasite can lead to inflammation and symptoms in rare cases. CASE A 36-year-old woman had an abdominal hysterectomy for menorrhagia, dyspareunia, and lower abdominal pain. Two small nodules from the posterior aspect of the left bro...

A cohort of children presented with pelvic inflammatory diseases (gastrointestinal and/or genitourinary surgical conditions) and had concomitant infection with E. vermicularis. To find out this relationship, a total of 135 patients suffering from different gastrointestinal and genitourinary surgical conditions were selected from Departments of Surgery and Gynecology. They were subjected to stoo...

Stool and cellotape anal swab examinations were carried out in August 1997 on handicapped people at an institution located in Chorwon-gun, Kangwon-do, Korea. A total of 112 stool samples (78 males and 34 females) revealed three cases of Trichuris trichiura infection and one case of Enterobius vermicularis infection. Other helminth eggs were not detected. The overall prevalence rate was 35.7% (3...

A high incidence of infection with the threadworm Enterobius vermicularis has been demonstrated in a group of children with allergic asthma, but also in a non-allergic group. There was no evidence of infection with any other helminth parasites. Presence or absence of threadworm infection was not clearly correlated with differences in total serum IgE level in either allergic or non-allergic chil...

While the presence of pinworm eggs in archaeological samples has been reported by many researchers in the New World, those have been detected very scarcely in the Old World, especially in East Asian countries. In fact, many parasite species were recovered from the archeological remains in Korea, eggs of Enterobius vermicularis had not been found. Recently, a female mummy buried in the 17th cent...

The status of pinworm (Enterobius vermicularis) egg positive rate of primary school children in Geoje island was investigated by using adhesive cellotape anal swap method, in September, 2002. Total egg positive rates of E. vermicularis were 9.8% (74/754) and those of male and female were 10.8% and 8.7%, respectively. Among three schools examined, Myeongsa primary school showed the highest egg p...

BACKGROUND Enterobius vermicularis infection is a prevalent intestinal parasitic disease in children. In this study, we explored the epidemiological status and risk factors for E. vermicularis infection in children in southern China. METHODS A cross-sectional survey was carried out in Gaozhou city, Guangdong province, China, in December 2011. Children aged 2-12 years from five schools partici...

(See pages 1030–1 for the Photo Quiz) Figure 1. The dimensions and the unilateral, flattened shape of the longitudinally sectioned structures clearly identify these as eggs of Enterobius vermicularis (thin arrows). The thick arrow indicates an elongated structure protruding from 1 of the eggs; this represents a hatching larva trapped in the inflammatory mass (original magnification, ϫ40). Diagn...
