title: A randomized trial of etretinate (Tigason) in palmoplantar pustulosis.
abstract: 5 patients with palmoplantar pustulosis (PPP) were randomized to 8 weeks of daily treatment with either oral etretinate, 1 mg/kg b.w. or placebo. Good or moderate effect was obtained in 18 or 20 patients on etretinate compared o 6 of 21 patients on placebo (p less than 0.001). Etretinate proved to be significantly superior to placebo with regard to influence on the individual symptoms and signs of pustulosis. All patients on etretinate experienced some side effects from the mucous membranes, but they were generally mild. Treatment was discontinued after 4 weeks in 3 patients for reasons unrelated to treatment, in 4 for lack of effect (all on placebo) and in 2 for side effects (both or etretinate). Etretinate is a good alternative to other systemic treatments of PPP.
