From the Guidelines
Tretinoin, a topical retinoid, is not a recommended treatment for molluscum contagiosum.
Standard Treatment Options
The standard treatment options for molluscum contagiosum include:
- Cryotherapy: a common treatment method, although it may be associated with postinflammatory hyperpigmentation or scarring 1
- Cantharidin: an effective treatment option, as indicated by open-label and observational studies 1
- Imiquimod 5% cream: applied topically for 3-6 months, although its efficacy is not well-established 1 Tretinoin, such as Retin-A 0.025-0.1% gel or cream, is primarily used for the treatment of acne, psoriasis, and photoaging, and its use in molluscum contagiosum is not supported due to lack of efficacy and potential for irritation.
Treatment Considerations
In patients with multiple lesions, care should be taken to identify and treat nascent lesions in order to reduce the risk of recurrence, but reduction of the viral load often allows the host immunologic response to eliminate residual virus 1. In adults, large and multiple molluscum lesions with relatively little conjunctival inflammation may indicate an immunocompromised state 1. Follow-up is not usually necessary unless the conjunctivitis persists, and referral to a dermatologist may be necessary for examination of other suspicious lesions 1.
From the Research
Treatment of Molluscum Contagiosum with Tretinoin
- Tretinoin is listed as a treatment option for Molluscum contagiosum in several studies 2, 3, 4.
- A comparative study of 5% potassium hydroxide solution versus 0.05% tretinoin cream for Molluscum contagiosum in children found that both treatments showed good response, but potassium hydroxide solution showed faster recovery 4.
- Tretinoin has been used to treat various dermatological conditions, including acne vulgaris and photodamage, and has demonstrated potential for treating other conditions such as Molluscum contagiosum 5, 6.
- The efficacy and safety of tretinoin in treating Molluscum contagiosum have been reported, with some studies showing promising results 2, 4.
Efficacy and Safety of Tretinoin
- Tretinoin has been shown to be effective in reducing the number of lesions in patients with Molluscum contagiosum 4.
- The safety profile of tretinoin is generally considered to be mild to moderate, with common adverse events including dermatitis and irritation 5, 6.
- Tretinoin has been used for 40 years in dermatology, with a significant amount of efficacy and safety data accumulated during this time 5.
Comparison with Other Treatments
- Tretinoin has been compared to other treatments for Molluscum contagiosum, including potassium hydroxide solution and imiquimod 3, 4.
- The choice of treatment for Molluscum contagiosum may depend on various factors, including the severity of the condition, the patient's age and health status, and the potential side effects of the treatment 2, 3.
