Aquagenic wrinkling

Aquagenic wrinkling of the palms (AWP) is a rare condition characterized by the rapid and transient formation of edematous whitish plaques on the palms on exposure to water (the so-called hand-in-the-bucket sign). The changes may be asymptomatic or accompanied by pruritic or burning sensations. First described in 1974 in patients with cystic fibrosis--and still primarily reported in these patients--this condition has been previously described only in females. Specific mutations in CFTR, the gene responsible for cystic fibrosis, have not been reported previously in patients with AWP.
