Plantar warts are among the most common skin conditions and are classically resistant to treatment. To perform an evidence-based evaluation of the efficacy and safety of available treatment options for plantar warts, we conducted a systematic review of PubMed and Cochrane databases to identify large interventional and observational studies involving more than 100 patients who were treated for plantar warts from inception to October 2020. We identified only nine contributions meeting our inclusion criteria (N ≥ 100), representing 1,657 adult and pediatric patients with plantar warts. Treatments included in this review were topical keratolytic agents, cryotherapy, laser therapies, and intralesional and systemic treatments. Our evidence-based review of the larger studies suggests keratolytic agents and destructive treatments, in particular salicylic acid and cryotherapy, remain the primary treatments for plantar warts. Treatment with pulsed dye laser had the lowest rate of recurrence. Newer treatments and intralesional treatments were not represented owing to lack of large studies involving these modalities.
