Abstract
Imiquimod 5% (Aldara™, 3 M Healthcare Ltd.) is a topically applied immune response modifier used in the treatment of superficial basal cell carcinoma, actinic keratosis, and genital warts. We reviewed the casenotes of 5 patients with histologically confirmed dysplastic lower lips who had been treated with topical imiquimod. Each patient was provided with a specially designed lower lip retractor to prevent spread of the cream. Treatment was stopped after 6 weeks or if an acute inflammatory reaction developed. The lower lip was biopsied 4 weeks later, and histologically the dysplastic changes had been reversed in all 5 patients. The lip retractor was well-tolerated, and prevented spread of the cream. Imiquimod 5% cream offers an alternative method to manage dysplastic lips. Our lip retractor is a simple and cost-effective method of isolating the lower lip and allowing application of topical agents. The method could equally well be used for agents other than imiquimod.
