Idiopathic Acquired Aquagenic Keratoderma Localized to Dorsum of the Hands

Acquired aquagenic keratoderma is a rare type of acquired palmoplantar keratoderma localized frequently and symmetrically to palms and occurs following short period of water exposure. A 42-year-old male patient applied to the outpatient clinic with complaints of elevated lesions and pores located on the hands and precipitated by water exposure and perspiration. On dermatological examination, whitish keratodermic macerated plaques and dilated punctae were observed over the dorsum of the hands following exposure of patient's hands to water for a short period of time. These findings regressed gradually after drying the hands. The patient was clinically diagnosed to have acquired aquagenic keratoderma. This case turned out to be interesting as it is the third case of acquired aquagenic keratoderma with localization on the dorsum of the hands, and it has been added to the ones already present in the literature. Here, we have reviewed the literature about acquired aquagenic keratoderma and reported our case. (Turkderm 2010; 44: 224-8)Wo
