A Comparative study between topical 15% potassium hydroxide and 20% Salicylic acid in treatment of multiple palmoplantar warts
Abstract Warts are one of the most common benign neoplasms. Warts are induced by over 100 types of human papillomavirus (HPVs) and can affect any race. Various treatments were considered to treat warts, of which topical salicylic acid and KOH are the most commonly used choices. Aim of the study To compare between the efficacy, safety and recurrence rate of topical 15% potassium hydroxide (KOH) and 20% Salicylic acid in the treatment of multiple palm plantar warts. Patients and methods study included 40 patients complaining of multiple palmar and/or planter warts 2 lesions at least. Each patient was treated by: Salicylic acid 20% used on one lesion and topical 15% KOH preparation used on another lesion. Assessment of patients’ response was done through clinical and dermoscopic examination. Results Salicylic acid results revealed that 5% of the treated lesions showed Clinical improvement without dermoscopic clearance, 40% showed Clinical clearance with dermoscopic remnants while 55% showed Clinical and dermoscopic clearance. KOH treated warts showed 5% of the treated lesions had clinical improvement without dermoscopic clearance, 25% showed clinical clearance with dermoscopic remnants while 70% showed clinical and dermoscopic clearance. Conclusion KOH therapy as well as patient satisfaction showed higher significant treatment response compared to salicylic acid therapy with less encountered side effects.
