Treatment of dyskeratosis follicularis Darier with the retinoic acid derivative Ro 10-9359 (Tigason).

The results of treatment of 29 patients with Darier's disease with the aromatic retinoid Ro 10-9359 are reported. Therapeutic tests for a period of more than 18 months seem to justify its use in Darier's disease. With a modest dose it is possible to keep the symptoms at an acceptable level, i. e., 50% clearing or more without too troublesome side effects. Because of the side effects the dosage must be fixed individually. It is pointed out that with the development of Ro 10-9359, an efficient remedy for Darier's disease has become available for the first time.
