Hormonal dependency in Darier disease.

Variation in the severity of keratosis follicularis relative to states of homonal change was noted in eight women with the disease. Observations included frequent onset near puberty, puberty, exacerbation during menses, and improvement while patients are pregnant or on oral contraceptive agents. It is proposed that states of relative estrogen excess are associated with quiescence of this skin disorder. In support of this hypothesis, three postpubertal women with Darier desease were observed to undergo significant improvement with the use of estrogen-dominant birth control pills.
