From the Guidelines
The recommended treatment for molluscum contagiosum in a 4-year-old male is watchful waiting, as the infection typically resolves on its own within 6-12 months without intervention. This approach prioritizes minimizing potential treatment-related morbidity and mortality, while also considering the quality of life for the child. According to a study published in Pediatrics in 2017 1, resolution of uncomplicated molluscum contagiosum typically occurs spontaneously in 6 to 12 months, although complete resolution of lesions can take up to 4 years.
Some key points to consider when deciding on a treatment approach include:
- The child's age and ability to tolerate potential treatment-related discomfort or pain
- The location and number of lesions, as well as their potential impact on the child's cosmetic appearance and self-esteem
- The presence of any underlying skin conditions, such as eczema, which may affect treatment choices
- The potential risks and benefits of active treatment options, such as cryotherapy with liquid nitrogen, which may be associated with postinflammatory hyperpigmentation or scarring 1
Active treatment options, such as 10% potassium hydroxide and cryotherapy with liquid nitrogen, have been used to treat lesions that are cosmetically bothersome or occur in patients with underlying skin conditions 1. However, these treatments may have similar efficacy in children, and cryotherapy may be associated with additional risks. Other treatment options, such as cantharidin, have shown promise in open-label and observational studies, but their effectiveness is not universally established 1.
It is essential to advise parents on preventive measures to avoid spreading the virus, such as avoiding shared towels and bathing items, and direct skin contact with lesions. The child should also be encouraged to avoid scratching lesions, which can spread the virus to other body areas. Ultimately, treatment decisions should balance the potential benefits and risks of intervention against the natural resolution timeline and the child's psychological comfort.

Treatment Options for Molluscum Contagiosum in a 4-Year-Old Male
The treatment for molluscum contagiosum in children can be challenging, particularly when the patient presents with multiple lesions or when lesions are symptomatic or highly visible 2. Several treatment options exist, including:
- Mechanical treatments (e.g. cryotherapy, curettage, pulsed dye laser therapy)
- Chemical treatments (e.g. cantharidin, potassium hydroxide, podophyllotoxin, benzoyl peroxide, tretinoin, trichloroacetic acid, lactic acid, glycolic acid, salicylic acid)
- Immune-modulating treatments (e.g. imiquimod, interferon-alpha, cimetidine)
- Anti-viral treatments (e.g. cidofovir)
Choice of Treatment
The choice of treatment method should depend on the physician's comfort level with the various treatment options, the patient's age, the number and severity of lesions, location of lesions, and the preference of the child/parents 3.
Cantharidin as a Treatment Option
Cantharidin is a commonly used treatment for molluscum contagiosum, and studies have validated its safety and efficacy 4. A prospective, randomized, double-blind, placebo-controlled pilot trial demonstrated that topical cantharidin was well-tolerated and associated with the resolution of molluscum contagiosum in pediatric patients 4.
Watchful Waiting
Watchful waiting can often be an appropriate management strategy for molluscum contagiosum, as it is generally a benign and self-limited infection that resolves spontaneously within 6 months to several years 5. However, some patients may require treatment due to discomfort, itching, or aesthetic concerns.
Key Considerations
When treating molluscum contagiosum in children, it is essential to consider the following factors:
- The number and location of lesions
- The prior experience of the treating physician
- The preferences of the child's parents or carers
- The potential risks and benefits of each treatment option 2
