Complications of pinworm infections are rare but may include:
- Bacterial infection around the anus or of the skin in the genital area. This is usually due to skin being irritated or bleeding from itching in these areas.
- Pinworm infection of the vagina (vulvovaginitis).
- Pinworm infection of the urethra (urethritis) or a secondary infection of the urinary tract (cystitis).
- Pinworm infection of the internal female sex organs (endometritis, salpingitis, and oophoritis).
- Inflammation inside the abdomen (peritonitis).
- An area of inflammation with a pocket of pus within the lower part of the intestine (rectal abscess).
- Irritation of the tissue covering the inside of the eyelid and eyeball (conjunctival sac irritation).
- Long-term inflammation and scar tissue (granulomas) in the prostate or liver. This is very rare.
- Prostate granulomas occur when pinworms travel up the urethra and settle in the prostate gland.
- Liver granulomas occur in females if pinworms travel through the reproductive system, get into the abdomen, and attach to the liver.
