Rare clinical variant of palmoplantar keratoderma
The article presents a clinical case of an 18-year-old patient with aquagenic keratoderma. This is a rare variant of acquired palmoplantar keratoderma, which is characterized by the appearance of dense waxy foci of white-yellow hyperkeratosis with swelling of the skin, lichenification, as well as plaques with a surface in the form of a «cobblestone pavement» after contact with water. Aquagenic keratoderma occurs in 44–80% of cases in patients with cystic fibrosis who have a homo- or heterozygous mutation δF508 in the CFTR gene responsible for regulating electrolyte transport. This clinical case is of interest to practicing dermatologists.Yu.A. Novikov, O.V. Pravdina, E.A. Zykova, S.R. Gamza
