Abstract
Pinworm, or Enterobius vermicularis, is the name of a tube worm that is an intestinal parasite found in humans, especially among children. Pinworm infection spreads easily and is more common in children between 5 and 10 years of age, people living in institutions and nursing homes, and people who have close contact with individuals from the afore-mentioned groups. Pinworms may also migrate from the anus to the vaginal area and cause vaginal itching, especially at night. In 2022, a 12-year-old girl from one of the villages of East Azarbaijan Province in Iran referred to one of the medical clinics with symptoms of itching and abnormal and purulent discharge from the vagina. In the parasitology laboratory, samples were taken from the perianal and vaginal areas using Graham’s test and an intravaginal swab. Eventually, Enterobius vermicularis eggs were detected.
