When is cryotherapy recommended for molluscum contagiosum?

Molluscum contagiosum causes small, firm, often dome-shaped bumps that can spread through skin contact or scratching. Many cases settle without a procedure, so observation can be reasonable when bumps are mild and not troublesome. Freezing is more likely to be discussed when lesions are persistent, irritated, spreading, or causing distress, or when reducing visible lesions is a priority.

Cryotherapy cools the bump enough to injure the affected tissue. Stinging, redness, swelling, blistering, crusting, and temporary colour change can follow. Treating one or several visible bumps does not guarantee that new lesions will not appear elsewhere.

Ask a clinician to confirm the diagnosis, especially if bumps are painful, inflamed, bleeding, or located near the eyes or genitals. Mention eczema, immune-system conditions, pregnancy, and any history of pigment changes or poor healing before treatment.

Keep treated skin clean and avoid picking. Cover bumps when practical, do not share towels or razors, and avoid close skin contact with uncovered lesions. Children should not return to activities with direct skin contact until the clinician has explained what is appropriate for the treated area.

Arrange medical review if bumps become very red, hot, painful, pus-filled, or rapidly more numerous. Seek prompt care for eye-area lesions, extensive involvement in someone with reduced immunity, or a wound after freezing that has worsening pain, spreading redness, fever, or delayed healing.

Ask whether watching the bumps is reasonable, why freezing is preferred, how discomfort will be managed, and how to protect nearby skin. Discuss contagiousness during healing, school or sport precautions, pigment change, and what to do if new bumps appear.
