Efficacy of 10% Potassium Hydroxide Solution Versus 10% Salicylic Acid Ointment in Treatment of Molluscum Contagiosum - the Low - Cost Dermatologic Therapy in Vietnam

BACKGROUND: Molluscum contagiosum is a common viral disease primarily affecting children. AIM: The objective is to compare the efficacy of 10% potassium hydroxide (KOH) solution versus 10% salicylic pomade in the treatment of molluscum contagiosum. METHODS: Clinical trials on 70 patients were randomised into 2 groups: 39 patients treated with 10% KOH solution and 31 patients treated with 10% salicylic pomade. The evaluation was based on the complete clearance of lesions, side effects and complications of the drug. RESULTS: The clearance of all lesions after 2, 4, 6, 8 weeks of treatment in both groups were 7.7%; 23.1%; 53.8%; 79.5% and 0%; 3.2%, 9.7% 22.6%, respectively (p < 0.05). Side effects were seen in both groups include burning (76.9% versus 19.4%; p < 0.05); redness (59% versus 14%; p < 0.01); desquamation (12.8% versus 19.3%; p < 0.05). CONCLUSION: The efficacy of KOH solution in the treatment of MC was better than that of salicylic pomade and both products are safe, effective, and easy to apply at home.
