T. Schreiner et al., TOPICAL APPLICATION OF TRETINOIN, INTERFERON-BETA AND THEIR COMBINATION IN THE TREATMENT OF FLAT WARTS, Journal of dermatological treatment, 6(1), 1995, pp. 17-19
Flat warts, mainly caused by human papillomavirus types 3 and 10, have
a high rate of spontaneous remission, Those warts that do not disappe
ar by themselves can be very difficult to treat, In our study we compa
red the efficacy of topical tretinoin, topical interferon beta and the
combination of both substances in the treatment of flat warts. The co
mbination of both substances proved to be considerably more effective
than either alone.
