Molluscum Contagiosum

Pronounced: mo-lus-kum kon-ta-je-o-sum

En Español (Spanish Version)

Definition

Molluscum contagiosum is a viral infection of the skin. It is caused by a virus that is a member of the poxvirus family. The molluscum virus is spread through skin-to-skin contact. In children, the areas most commonly affected are the face, neck, arms, and hands. In adults, this infection is considered a sexually- transmitted disease, and the genitals and surrounding skin are the areas most commonly affected.

Causes

Contact with the molluscum virus causes this skin infection. Skin lesions occur two weeks to two months after infection.

Risk Factors

A risk factor is something that increases your chance of getting a disease or condition. Having skin-to-skin contact with an infected person is the primary risk factor for contracting molluscum contagiosum. Other risk factors include:

  • Indirect contact with an infected person through a swimming pool or bath or by sharing towels or clothing
  • Sexual contact with an infected person
  • Weakened immune system (eg, HIV/AIDS ) or broken skin (eczema) increases risk for getting disease, and causes more severe symptoms

Symptoms

Skin lesions are the primary symptom of molluscum contagiosum. If you experience a similar skin lesion, don’t assume it is due to molluscum contagiosum, these lesions may be caused by other health conditions, and it is important that you see your physician.

Molluscum contagiosum skin lesions usually have the following characteristics:

  • Small, dome-shaped bumps with dimpling in center
  • Painless, but may be itchy or tender
  • At first appear translucent, pearly or flesh-colored and later may turn gray and drain
  • White or waxy substance in center of lesion
  • Usually multiple lesions in groups
  • Face, trunk, arms, and legs are common sites in children
  • Genitals, abdomen, and inner thigh are common sites in adults
  • Can last from several weeks to several years

Diagnosis

Diagnosis of molluscum contagiosum is usually made based on the appearance of the lesions. Sometimes a biopsy will be taken to look at under a microscope to confirm the diagnosis. Your doctor may refer you to a dermatologist, a doctor who specializes in skin conditions.

Treatment

Left untreated, this disease usually resolves within six months. In untreated HIV infected patients, the lesions usually persist and spread indefinitely. Your doctor may recommend removal of the lesions in order to prevent spreading, or to avoid infecting others.

Treatment options include the following:

Surgical Removal

The lesions can be removed by cutting them off the surface of the skin with a curette .

Chemical Treatment

Similar to treating warts, chemicals are placed directly on the lesions to remove them. Common treatments include podophyllin, cantharidin, phenol, silver nitrate, trichloracetic acid, and iodine.

Cryotherapy

This method uses cold to freeze the lesions off of the skin. Liquid nitrogen may be used for this treatment.

Medical Treatment

A retinoid or imiquimod cream may be used separately or in combination.

Prevention

This disease is contagious. Take the following measures to reduce your risk of exposure to the virus:

  • Avoid contact with an infected person; this includes sharing towels, clothing, baths, and pools
  • Avoid sexual contact with an infected person

If you have the disease, reduce the risk of spread by not touching the lesions, not scratching, and washing your hands promptly if you do.
