Clinical improvement of papules was statistically significant, whereas scaling and erythema did not change significantly. Side-effects of the study medication were only minimal and easily controlled by reduction of the application frequency. Biopsies for immunohistochemical examination were taken from representative skin lesions, one before and one from each side after treatment. Keratins 4 and 13 were induced by the treatment with topical 13-cis-RA in three and two patients, respectively. In conclusion, topical 13-cis-RA 0.1% cream is a well-tolerated therapy for Darier's disease. Induction of keratins 4 and 13 seem...
