Molluscum Contagiosum Treatment

Molluscum contagiosum is a common viral skin infection that causes small, raised bumps on the skin. It is highly contagious and spreads through direct skin-to-skin contact. In children, it is extremely common and usually harmless. In adults, however, molluscum contagiosum affecting the genital area is typically considered a sexually transmitted infection (STI) because it is most often passed through sexual contact.

Although the condition often clears naturally over time, treatment may be recommended to prevent spread, reduce discomfort, and improve cosmetic appearance.

What Is Molluscum Contagiosum?

Molluscum contagiosum is caused by a virus from the poxvirus family. It is related to the virus that causes genital warts, although it behaves differently and is generally less persistent.

The virus infects the skin’s surface and causes distinctive lesions. It does not usually cause systemic illness or long-term health problems in healthy individuals.

How Is Molluscum Spread?

Molluscum spreads through:

  • Direct skin-to-skin contact

  • Sexual contact (in adults)

  • Sharing towels or clothing

  • Close physical contact within households

In children, transmission often occurs through play, shared baths, or sports. In adults, lesions in the genital or inner thigh area are usually acquired through sexual contact.

Because the virus lives in the surface layers of the skin, it can spread from one part of the body to another through scratching or shaving.

Symptoms of Molluscum Contagiosum

The main symptom is the appearance of small, firm, dome-shaped bumps on the skin.

These lesions:

  • Are usually flesh-coloured or pearly

  • Have a characteristic central dimple (umbilication)

  • May contain a white, waxy core

  • Range from 2–5 mm in size

Lesions are typically painless but may become itchy, inflamed, or red if irritated.

In adults, molluscum often appears on:

  • The pubic region

  • Inner thighs

  • Lower abdomen

  • Penis or vulva

In children, lesions may occur anywhere on the body, particularly the arms, trunk, and face.

How Long Does Molluscum Last?

In most cases, molluscum contagiosum clears on its own within 6 to 18 months as the immune system gradually eliminates the virus.

However, during this time:

  • Lesions can spread

  • New bumps may appear

  • Transmission to others remains possible

For many adults, especially when lesions are visible in the genital area, waiting for spontaneous resolution is not ideal.

Is Molluscum an STI?

Molluscum contagiosum is not exclusively an STI, but in adults, it is often treated within sexual health services because genital lesions are commonly transmitted during sexual contact.

If molluscum is diagnosed in a sexually active adult, we may recommend:

  • Screening for other STIs

  • Discussion about partner notification

  • Advice on reducing transmission

This ensures comprehensive sexual health care.

Diagnosis

Diagnosis is usually clinical. The appearance of the characteristic dome-shaped bumps with a central dimple is typically sufficient.

Laboratory tests are rarely required.

Because other conditions — such as genital warts, folliculitis, or herpes — can sometimes appear similar, professional assessment ensures accurate diagnosis and appropriate treatment.

Treatment Options for Molluscum

Although molluscum often resolves without treatment, many patients prefer active removal.

Reasons for treatment include:

  • Preventing spread

  • Cosmetic concerns

  • Reducing irritation

  • Faster resolution

Cryotherapy (Preferred Treatment)

Cryotherapy is the most commonly recommended treatment in adults. This involves applying liquid nitrogen to freeze the lesions.

Cryotherapy:

  • Destroys infected tissue

  • Stimulates immune response

  • Is quick and performed in clinic

  • May require more than one session

Mild discomfort during treatment is common, and temporary redness or blistering may occur.

Other Treatment Approaches

In some cases, alternative options may include:

  • Topical treatments

  • Curettage (physical removal)

  • Monitoring without intervention

The best approach depends on the number, location, and size of lesions.

Preventing Spread

To reduce transmission:

  • Avoid shaving affected areas

  • Avoid scratching lesions

  • Do not share towels or bedding

  • Cover lesions where possible

  • Avoid sexual contact until treated

Because the virus spreads easily through skin contact, treating lesions early reduces onward transmission.

When to Seek Medical Advice

You should book an appointment if:

  • You notice small, dome-shaped bumps with a central dimple

  • Lesions are spreading

  • The rash is located in the genital area

  • You are unsure whether the bumps are molluscum or another condition

  • Symptoms are causing distress

Prompt assessment provides reassurance and allows discussion of treatment options.

Molluscum in Children vs Adults

In children, molluscum contagiosum is extremely common and usually managed conservatively. In adults, particularly when lesions appear in the genital area, sexual transmission is more likely, and treatment is often preferred.

In individuals with weakened immune systems, molluscum may be more widespread and persistent, requiring specialist management.
