Therapeutic efficacy and safety of three different modalities in pediatric patients with plantar warts.

Human papillomavirus infection is relatively common in communities. Thus, determining an effective and painless treatment method, especially in pediatric patients is of utmost importance. This study aimed to compare the outcomes of three different methods of treating plantar warts in pediatric patients. Children with verruca plantaris treated with a salicylic acid-lactic acid combination once daily (SA/LA 1), a salicylic acid-lactic acid combination applied in three to seven layers under occlusion every 3 days (SA/LA 2), or a combination of 5-fluorouracil (0.5%) and salicylic acid (10%) (SA/5-FU) were evaluated retrospectively. Treatment responses and recurrence rates were also evaluated after a minimum of 4 months. Among the 98 children with verruca plantaris, 19 were treated with SA/LA 1, 53 were treated with SA/LA 2, and 18 were treated with SA/5-FU; the eight patients who received cryotherapy were excluded. The mean treatment duration was significantly shorter in the SA/LA 2 group than in the SA/LA 1 group and the SA/5-FU group. (p = 0.000 for both) Application of a salicylic acid-lactic acid combination in multiple layers under occlusion is a safe, painless, and effective treatment method for plantar warts in children.
