Dermatoscopy as an adjunctive diagnostic tool in aquagenic syringeal acrokeratoderma

Aquagenic syringeal acrokeratoderma (ASA) is a rare skin disorder of the palms and/or soles, characterized by whitish papules with occasional pruritus or pain sensation. Herein we report a 27-year-old man with a diagnosis of ASA based on clinical and histopathological features, and describe the dermatoscopic features consistent with threefold enlarged sweat duct pores compared with a normal-looking palmar skin area. As far as we are aware, dermatoscopic features of ASA have not been reported so far.
