Molluscum contagiosum

Molluscum contagiosum is a skin infection that causes small pearly or flesh-colored bumps. The center of the bump is often indented. The infection is caused by a virus. The virus is easily spread but is not harmful.

This infection is most common in children. But teens and adults can also get it, often from taking part in sports like wrestling and gymnastics or from sexual contact. It can occur in healthy people. But when it occurs in people with a weak immune system, the symptoms may be worse.

Molluscum contagiosum causes small pearly or flesh-colored bumps that don't cause pain. The bumps are round with a dimple in the center. They may itch, become inflamed, and turn reddish as your body fights the virus.

To diagnose molluscum contagiosum, your doctor will do a physical exam and may take a sample of the bumps for testing. If you have bumps in your genital area, your doctor may check for other sexually transmitted infections, such as genital herpes.

Molluscum contagiosum doesn't usually need to be treated. The infection usually goes away within 6 to 18 months.

But people sometimes ask that the condition be treated, especially if it lasts a long time—the bumps can sometimes last for several years. And doctors usually recommend treatment for any bumps in the genital area to prevent spread to sexual partners. People with weakened immune systems also are usually treated.

If you have treatment, your choices may include:

• Freezing the bumps. This is called cryotherapy or cryosurgery.
• Scraping off the bumps. This is called curettage.
• Putting medicine on the bumps. Some medicines, such as cantharidin, are applied by the doctor. Other medicines are applied at home by the patient.

You may choose to not have your child treated. But if your child has treatment, talk to the doctor about how to prevent pain, scarring, and changes in skin color (pigment) from treatment.

• Teach your child not to share personal items like clothing or sports gear. This includes towels, washcloths, helmets, and goggles.
• Keep the bumps covered with a bandage, medical tape, or clothing when your child is around people. Have your child use waterproof bandages when swimming or playing sports.
• Teach your child to avoid spreading the bumps to other parts of the body. For example, teens should avoid shaving near the bumps. And don't scratch or try to remove the bumps.
• Sexually active teens should not have sex if they have bumps in their genital area. Having treatment can help avoid spreading them to any sexual partners.
• If your child's doctor prescribes medicine, use it exactly as directed.
