For molluscum contagiosum that persists or is symptomatic, which treatment option may be used with caution?

• A. Trichloroacetic acid 25% to 50% solution
• B. Liquid nitrogen cryotherapy
• C. Reassuring wait-and-see
• D. Curettage

Answer: (A)

Molluscum contagiosum in children often resolves on its own, but when lesions persist or cause symptoms, treatment seeks to remove or destroy the infected tissue while minimizing pain and scarring. Trichloroacetic acid at 25–50% is a chemical cauterant that can effectively destroy individual lesions with controlled application. It is used with caution because it is caustic and can irritate or burn surrounding skin, leading to chemical burns, postinflammatory pigment changes, or discomfort if it contacts non-target skin or mucous membranes. When performed by a clinician, small, targeted applications to each lesion, away from normal skin, eyes, and mucosa, may require repeat sessions but can reduce lesion burden with relatively limited invasiveness compared with some other methods. In contrast, cryotherapy, curettage, or opting for reassurance alone each carry their own drawbacks—pain and blistering with cryotherapy, invasiveness and potential scarring with curettage, or the possibility of ongoing symptoms with watchful waiting—so the chemical cauterization approach is the one best suited for a cautious, targeted treatment when symptoms persist.
