    General Discussion
    Keratosis follicularis, also known as Darier disease, is a rare, genetic skin disorder. Affected individuals develop skin lesions that consist of thickened, rough bumps (papules) or plaques that may also be greasy or have a brown or yellow crust. These hardened, scaly lesions are progressive and may gradually grow bigger or spread. The nails and mucous membranes are also affected in many cases. Additional symptoms may be present in some cases. Individuals may have periods of time when signs improve (remission), but the lesions usually recur (relapse). The specific problems vary from one individual to another. Keratosis follicularis is inherited as an autosomal dominant trait.
