What is Molluscum Contagiosum?
Molluscum contagiosum is a common viral skin infection that leads to the development of small, firm, and painless bumps on the skin. While often seen in children, adults can also be affected—especially through skin-to-skin contact, including sexual contact.
These growths are benign (non-cancerous) but contagious and can spread through direct contact or shared items like towels, razors, or gym equipment.
Key Characteristics
Texture: Smooth, firm, and dome-shaped with a central dimple or “core”
Shape: Round or oval bumps
Color: Flesh-colored, white, or pink
Size: Typically 2–5 millimeters in diameter
Sensation: Usually painless but may become itchy, red, or inflamed
Molluscum may appear singly or in clusters and can develop on the genital area, thighs, abdomen, armpits, or face. The virus can spread across the skin or to others through contact.
What Causes It?
Molluscum contagiosum is caused by a poxvirus known as the molluscum contagiosum virus (MCV). It spreads through:
Skin-to-skin contact (including sexual contact)
Sharing personal items (towels, razors, clothing)
Autoinoculation (spreading from one part of your body to another)
Weakened immune systems may lead to more widespread or persistent cases
It is more common in people with eczema, immune suppression, or those who are sexually active.
When Should You See a Doctor?
While molluscum often resolves on its own over months to years, medical evaluation is recommended if:
Lesions become red, swollen, or painful
There's rapid spreading or involvement of the genital area
You are immunocompromised or have a skin condition like eczema
You're concerned about appearance or transmission
Lesions don’t improve or seem to worsen
A dermatologist can typically diagnose molluscum contagiosum by visual examination, and in rare cases, a biopsy may be done to confirm the diagnosis.
Treatment Options
Treatment is not always necessary, but may be recommended to reduce spread, discomfort, or for cosmetic reasons. Options include:
Cryotherapy (freezing with liquid nitrogen)
Curettage (removal by scraping)
Topical medications (e.g., cantharidin, imiquimod, or retinoids)
Laser therapy (in resistant or widespread cases)
Avoid picking or scratching lesions, as this can spread the virus or lead to secondary infection.
Living With Molluscum
Molluscum contagiosum in adults is treatable and usually temporary. Practicing good hygiene and avoiding skin contact with others during outbreaks can prevent spread. Most cases resolve within 6 to 12 months, though some may last longer.
Regular skin care and communication with your dermatologist can help manage symptoms and reduce the risk of recurrence.
If you notice a new or changing spot on your skin, especially one that feels rough, dry, or scaly, it's important to get it evaluated. Early intervention can prevent complications and ensure the health of your skin.
