Imiquimod (CAS NO.99011-02-6) is a prescription medication that acts as an immune response modifier. Imiquimod is approved to treat actinic keratosis, superficial basal cell carcinoma, and external genital warts. It has also been tested for treatment of molluscum contagiosum, vulvar intraepithelial neoplasia, common warts that have proven difficult to treat and vaginal intraepithelial neoplasia.Outstanding cosmetic result has resulted from the treatment of both large superficial basal cell carcinoma and squamous cell carcinoma in-situ, but the morbidity and discomfort of the treatment can be severe. Focal recurrence of tumor has been seen after imiquimod treatment, but appear to be amenable to surgical excision.
Imiquimod can also cause subclinical lesions to become visible. This unmasking effect is felt to be of clinical benefit as lesions that may have otherwise have been missed are being treated. Photographs of actinic keratosis and basal cell carcinomas before, during and after treatment show the unmasking of subclinical disease.
