title: Aquagenic keratoderma.
abstract: Aquagenic keratoderma has been described as a transitory condition involving young females and defined clinically by the appearance of palmar lesions accentuated after immersion in water. According to previous case reports, these lesions are characterized histologically by hyperkeratosis and dilated eccrine ducts. Some aberration in the eccrine ducts has been suggested as a possible pathogenic mechanism. We report a new case in a female adolescent. With regard to the normal aspect of the epidermis in our case, the clinical changes should be ascribed to a structural alteration of the horny layer without any visible microscopy change or functional alteration of the stratum corneum involving the organism in the adolescence period.
