Definition
Molluscum contagiosum is a skin infection.
Causes
The molluscum contagiosum virus (MCV) causes the infection. MCV spreads from contact with someone who has it. This can happen through:
- Touching skin to skin
- Having sex
- Sharing items such as a towel, or yoga or wrestling mat
It can also spread from one part of your body to another. This happens mainly with your hand.
Risk Factors
Your chances of molluscum contagiosum are higher if you have:
-
Other skin problems such as
atopic dermatitis
-
Problems with your immune system from:
- HIV
infection
- Medicines
- Leukemia
Symptoms
Bumps generally appear on the face, trunk, arms, and legs of children. The groin, belly, and inner thighs are common places on adults.
Molluscum contagiosum may cause:
- Small, flesh-colored, dome-shaped bumps with dimpling in middle
- Itching
- Soreness
- Clear, pearly, or flesh-colored bumps that may turn gray and drain
- White or waxy substance in the middle of bump
- Many bumps clustered together
These problems may last from many weeks to many years.
Diagnosis
The bumps on your skin point to molluscum contagiosum. A biopsy can rule out other causes. A skin sample is checked under a microscope.
Treatment
In most cases, molluscum contagiosum doesn’t need care. It will go away on its own within 6 to 9 months.
In others, the bumps may linger or spread. This can be more of a problem for people with HIV. Your doctor may remove the bumps. This will help lower the chances of spreading it on you or to other people.
Procedures may involve:
- Cryotherapy—extreme cold removes the bumps
- Curettage—cutting out the bumps
- Laser surgery—use of steady or pulsed high intensity light
- Placing chemicals on your skin to remove the bump
Prevention
To lower your chances of getting molluscum contagiosum, avoid contact with someone who has it.
If you have it, don’t:
- Have contact with others.
- Play sports that involve contact with others.
- Share your items with others.
