Molluscum contagiosum in children: comparative treatments

Introdução: Molluscum contagiosum is a dermal viral infection commonly occurring in childhood. Although self-limited, this disease is contagious and involves complications such as pruritus, eczema and bacterial superinfection. A therapeutic approach is often required, and treatment selection depends on its effectiveness and patient tolerance.
Objective: Compare 3 treatments in children regarding efficacy, adverse effects and psychological impact, in efforts to customize the treatment approach.
Methods: Randomized, comparative and prospective study of patients aged 3 to 15, divided into 3 groups.The trunk and face were the most frequently affected sites. Group 1 was treated with 10% potassium hydroxide,Group 2 with a combination of salicylic and lactic acids, and Group 3 with curettage. Parental satisfaction regarding comfort and treatment cost was assessed in each group.
Results: Although some tendencies could be identified, the study did not detect statistical differences between the treatment groups. Group 1 experienced more pain, and a greater number of patients with complications at the end of the follow-up period. Group 3 patients were more cooperative in their treatment, since this method was the quickest and presented the fewest side effects, resulting in greater parental satisfaction. Discussion: Curettage (Group 3) and the combination of salicylic and lactic acids (Group 2) were equally effective, although the results for Group 2 were more gradual.
Conclusion: Treatment of this condition must be individualized, taking the patients’ preference, tolerance and availability of time into consideration.
