What is molluscum contagiosum?
Molluscum contagiosum is a viral disease of the skin. It causes small pink or skin-colored
bumps on the skin. It is not harmful and usually does not have any other symptoms.
The virus is inside the bumps and is mildly contagious. These bumps usually clear
over an extended period of time.
What causes molluscum contagiosum?
Molluscum contagiosum is caused by a virus called the poxvirus. It is most common
in children and adolescents, although it can affect adults. The virus usually is spread
through skin-to-skin contact with an infected person. People with weakened immune
systems, young children, and people living in warm, humid climates are less resistant
to molluscum contagiosum.
What are the symptoms of molluscum contagiosum?
The bumps are small and are usually pink or skin-colored. Eventually, the bumps tend
to develop a small sunken center. The lesions can form alone or in groups or clusters.
They are not harmful, but may cause some cosmetic concern for the individual if they
appear on the face or other visible areas.
How is molluscum contagiosum diagnosed?
Molluscum contagiosum is usually diagnosed based on a medical history and physical
exam. The lesions are unique and are usually diagnosed on physical exam. Additional
tests are not routinely ordered, though occasionally your healthcare provider may
want to perform a skin biopsy to confirm the diagnosis.
Treatment for molluscum contagiosum
Specific treatment for molluscum contagiosum will be discussed with you by your healthcare
provider based on:
Your age, overall health, and medical history
Extent of the condition
Your tolerance for specific medicines, procedures, or therapies
Expectations for the course of the condition
Your opinion or preference
In most cases, the lesions will heal without treatment over a period of 6 to 12 months.
The virus can last up to 4 years and may leave scars. The best way to avoid this disease
is by following good hygiene habits. For example, do not pick or scratch your skin
(or someone else's). Always practice good hand-washing hygiene. Additional treatment
choices may include:
Removal of the lesions, by using cryotherapy (freezing them off), a small blade, electric
sparks, or lasers
Use of topical medicines (to speed resolution of the lesions)
