[Treatment of psoriasis with an orally effective aromatic retinoid].

Results of treatment of psoriasis and various keratinizing dermatoses with an orally effective, aromatic retinoid are presented. Results in 39 of 55 psoriatic patients ranged from satisfactory to excellent. All side effects are restricted to hypervitaminosis A. The therapeutic margin of this new retinoid is clearly better than that of natural vitamin A and vitamin A acid preparations and other previously tested synthetic retinoids. Even after long-term treatment of 14 patients for more than 2 years no side effects of vital importance have as yet appeared.
