Treatment of warts with topical cidofovir in a pediatric patient.

Cidofovir is an antiviral nucleotide analogue with relatively new treatment capacities for dermatological conditions, specifically verruca vulgaris caused by human papilloma virus infection. In a 10-year old boy with severe verruca vulgaris recalcitrant to multiple therapies, topical 1% cidofovir applied daily for eight weeks proved to be an effective treatment with no adverse side effects. This case report, in conjunction with multiple published reports, suggests that topical 1% cidofovir is a safe and effective treatment for viral warts in pediatric patients.
