Wood's light as a noval diagnostic tool in aquagenic keratoderma

Aquagenic keratoderma, also known as aquagenic wrinkling of the palms, transient reactive papulotranslucent acrokeratoderma, or transient aquagenic hyper-wrinkling, is an uncommon disorder that affects the palms and occasionally the soles. It presents with translucent whitish to yellowish papules and increased wrinkling upon water exposure. The frequency of this condition is yet to be determined among the general population. However, it is frequently observed in patients among patients with cystic fibrosis or carriers of the cystic fibrosis gene, with frequency estimated to be up to 41%. In this paper, we report the utility and novelty of Wood's light as a bedside adjunct tool to aid in diagnosing aquagenic keratoderma. To our knowledge, this is the first case reporting the use of Wood's light in diagnosing aquagenic keratoderma.
