[Clinical, therapeutic and pathophysiological aspects of Darier's disease]

Darier Disease is a rare autosomal dominant inherited skin disorder classified as an acantholytic dermatosis. It manifests around puberty as brownish keratotic papules of skin folds and seborrheic areas, associated with onychopathy and mucosal involvementand have a chronic relapsing-remitting course with frequent exacerbations triggered by sun exposure, heat, friction, or infections. Darier patients have an increased risk of neuropsychiatric disorders, type 1 diabetes and heart failure. Short-term management relies on antibiotics/antiviral, topical corticosteroids and/or retinoids. Moisturizers, sun protection and avoiding triggers are essential for long-term management. Conventional long-term treatment is not standardized and many topical treatments, physical and surgical measures and systemic treatments are described in the literature.
