Preliminary Observations on the Use of Topical Tazarotene to Treat Basal-Cell Carcinoma

Abstract
Tazarotene is a novel receptor-selective retinoid originally developed for the topical treatment of mild-to-moderate plaque psoriasis.1 On the basis of recent hypotheses about the effects of this agent on the differentiation and proliferation of keratinocytes,2 we performed an open-label clinical trial to evaluate the efficacy and tolerability of topical tazarotene (0.1 percent in gel) in the treatment of basal-cell carcinoma.
