A 21‐year‐old woman presented with a 1‐month history of whitish bubbling of the palms after brief exposure to water. The symptoms arose within 3–5 min after immersion in water, as a white sponge‐like appearance, and resolved after a variable drying period. She was otherwise healthy and did not complain of hyperhidrosis. There was no family history of similar lesions. Physical examination revealed a healthy appearance of the palms; however, 5 min after immersion of the hands in warm water, the central part of the left palm became swollen and tiny white papules with dilated puncta appeared. The right palm also showed similar changes. These asymptomatic papules with a tendency to coalesce became more prominent with prolonged exposure ( Figs 1 and 2). The lesions resolved completely approximately 30 min after removal of the hands from water. A biopsy taken from the lesional skin revealed dilatation of intraepidermal eccrine ducts and a spongy appearance in the corneal layer ( Fig. 3). A diagnosis of aquagenic syringeal palmar keratoderma was made on the basis of these clinical and histopathologic findings. A short course of treatment with topical aluminum chloride resulted in a remarkable response in 1 week. She had no recurrence after 1 year. 1Confluent white papules on the palms2Magnified appearance of the lesions on the right palm3Close‐up of a dilated acrosyringium and increased translucency of the keratin layer above it.
