Imiquimod 5% cream as a therapeutic option for extramammary Paget's disease

Abstract

A wide local excision is the standard treatment for extramammary Paget's disease (EMPD), though this treatment often leads to permanent anogenital mutilation and functional impairment. The purpose of our study is to evaluate the efficacy and safety of the topical application of imiquimod 5% cream for non-invasive EMPD. We examined nine patients with EMPD. Eight of the nine patients were treated with imiquimod 5% cream three times per week for 16 weeks; one case was treated for 6 weeks. The response rate was 100% including five complete remissions. Local irritation was observed in three patients, which was controlled by a provisional withdrawal of the treatment. These results suggest that imiquimod 5% cream may be considered an alternative therapeutic option for the treatment of non-invasive EMPD.
