ABSTRACT

Although treating contagious molluscum with 5% potassium hydroxide solution is common, some studies challenge its efficacy. Ten patients (aged 4-13) with a total of 141 lesions were evaluated. After 28 days of treatment there were 105 lesions (75% of the initial amount), none of which achieved total resolution. Persistent lesions were curetted in up to two sessions; 28 of the 105 lesions remained after treatment. The percentages of reduced or completely resolved lesions were higher for curettage than potassium hydroxide (71% x 9%, p = 0 .01 vs. 80% x 0%, p = 0.02).


O uso da solução de hidróxido de potássio a 5% para tratar molusco contagioso é comum, embora existam estudos discordantes sobre sua eficácia. Avaliamos 10 pacientes entre quatro e 13 anos. O número de lesões iniciais totalizava 141. Após 28 dias de tratamento havia 105 lesões (75% da carga inicial), e nenhuma obteve clareamento total. As lesões persistentes foram curetadas em até duas sessões. De 105 lesões restaram 28. A porcentagem de redução das lesões e a proporção de resolução completa foram superiores para a curetagem (71% x 9%; p = 0,01 / 80% x 0%; p = 0,02).
