To evaluate and compare the safety and efficacy of 10% potassium hydroxide (KOH) solution and salicylic and lactic acid (SAL + LAC) combination in the treatment of molluscum contagiosum (MC).


26 patients with MC randomized into two treatment groups. 12 patients treated with 10% KOH solution and 14 patients treated with SAL + LAC combination for 6 weeks. Parents of patients were instructed to apply medication once daily only to lesions at study onset. Assessment of response of the treated lesions and side effects was performed at 2, 4 and 6 weeks of the treatment. Newly acquired lesions were not included in the study.


At the end of therapy, 83.3% (n = 10) of KOH group demonstrated complete remission and 16.7% (n = 2) of them showed partial remission; four patients (33%) developed new lesions during the study. All the patients in the SAL + LAC combination group (100%) demonstrated complete remission of study entry lesions at the end of 6 weeks with five patients (35%) acquiring new lesions during the study. Minor side effects were observed in two groups.


10% KOH solution and SAL + LAC combination were found to be equally effective in the treatment of MC in children.
