Some case reports have suggested that severe pinworm infection may be associated with an increased risk of appendicitis. [1]

Scratching the itchy area may cause eczema or a bacterial infection around the rectum. In girls, pinworm infection can spread to the vagina and may cause a vaginal discharge.

E vermicularis can mimic other disease processes and, although rare, can lead to serious infectious complications such as tubo-ovarian abscesses. [5]

The following complications have also been noted: appendicitis, endometritis, salpingitis, urethritis, urinary tract infection, and vulvovaginitis.
