Pinworm Infestation
Symptoms and Signs of Pinworm Infestation
Most infected people have no symptoms or signs, but some experience perianal pruritus and develop perianal excoriations from scratching. Secondary bacterial skin infection may occur. Rarely, migrating female worms ascend the human female genital tract, causing vaginitis and, even less commonly, peritoneal lesions. Many other conditions (eg, abdominal pain, insomnia, seizures) have been attributed to pinworm infestation, but a causal relationship is unlikely. Pinworms have been found obstructing the appendiceal lumen in cases of appendicitis, but the presence of the parasites may be coincidental.
