[Aquagenic keratoderma: 3 new cases and a review of the literature].

Aquagenic keratoderma is a rare type of transient acquired keratoderma that is triggered or exacerbated by immersion of the palms or soles in water. It is characterized by whitish or translucent papules with central punctate depressions that coalesce in macerated edematous plaques. It appears within a few minutes of exposure to water and subsides soon after drying. We describe 3 new cases of aquagenic keratoderma in a 28-year-old man with a history of Behçet disease, an 18-year-old woman, and a 20-year-old man. We discuss the clinical and histopathologic features, treatment options, and course of the lesions in the cases described in the literature.
