What are the recommended treatments for molluscum contagiosum?

Molluscum Contagiosum Treatment

For symptomatic molluscum contagiosum, physical removal through incision and curettage (aggressive enough to cause bleeding), simple excision, excision with cautery, or cryotherapy is the recommended treatment approach. 1, 2, 1

Treatment Decision Algorithm

Symptomatic Patients (Recommended to Treat)

Physical destruction methods are the guideline-endorsed first-line approach:

• Incision and curettage (must be aggressive enough to cause bleeding)
• Simple excision
• Excision with cautery
• Cryotherapy

1, 2, 1, 2

Critical technical point: When treating multiple lesions, identify and treat nascent (early) lesions to reduce recurrence risk. Reducing viral load allows the host immune response to eliminate residual virus 1, 2, 1.

Asymptomatic Patients (Observation Acceptable)

Molluscum lesions spontaneously resolve but can persist for months to years. Observation is justified for asymptomatic infection 3.

Special Populations

Immunocompromised Adults: Large and multiple molluscum lesions with relatively little conjunctival inflammation indicate immunocompromised state. Refer to dermatology for examination of other suspicious lesions 1, 2, 1.

Pediatric Patients with Cosmetic Concerns or Eczema: The 2017 Pediatrics guideline notes that 10% potassium hydroxide and cryotherapy with liquid nitrogen have been used for cosmetically bothersome lesions or patients with underlying eczema, with similar efficacy 3. However, cryotherapy may cause postinflammatory hyperpigmentation or scarring 3.

Emerging Evidence on Topical Therapies

While the most recent 2024 ophthalmology guidelines 1 prioritize physical destruction, newer research provides additional context:

• Salicylic acid + lactic acid 16.7%, cantharidin 0.7%, and potassium hydroxide 10% showed superior efficacy in a 2026 pediatric network meta-analysis 4
• Berdazimer gel 10.3% and cantharidin 0.7% are FDA-approved therapies achieving meaningful lesion clearance (>50%) within 6 weeks to 3 months 5
• Imiquimod was NOT shown to be beneficial compared with placebo in randomized controlled trials 3

Important Clinical Pitfalls

1. Conjunctivitis resolution timing: When molluscum causes conjunctivitis/keratitis from eyelid lesions, the conjunctivitis may require weeks to resolve after elimination of the lesion 1, 2, 1

2. Follow-up: Not usually necessary unless conjunctivitis persists 1, 2, 1

3. Avoid ineffective treatments: Imiquimod has failed to show benefit in controlled trials despite being commonly discussed 3

4. Natural history: Resolution typically occurs spontaneously in 6-12 months, though complete resolution can take up to 4 years 3

Treatment Selection Framework

Choose physical destruction (curettage, excision, cryotherapy) when:

• Patient is symptomatic
• Lesions cause conjunctivitis/keratitis
• Patient/family desires treatment to reduce transmission or disease burden

Consider observation when:

• Patient is asymptomatic
• Lesions are not causing ocular complications
• Patient/family accepts watchful waiting

Consider topical therapies (KOH 10%, cantharidin 0.7%, salicylic/lactic acid) when:

• Physical destruction is not feasible
• Patient preference for non-invasive approach
• Multiple lesions make physical destruction impractical
