Five psoriatic patients developed papular lesions of palms and soles, shortly after beginning treatment with etretinate. Histological examination in two cases was insignificant. The lesions disappeared without tapering the dose of etretinate. The fact that lesions appeared and subsided within a short period may explain why this unusual adverse reaction of etretinate therapy has not been reported previously.
