Etretinate Improves Localized Porokeratosis of Mibelli

A 60-year-old woman with plaque-type psoriasis of 30 years' duration was treated with etretinate. The lesion resolved while the patient was on the drug and continued to resolve after she had discontinued therapy. The continuation of resolution after the patient had discontinued the drug is probably due to its long half-life.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65498/1/j.1365-4362.1985.tb05777.x.pd
