Author Affiliations


Arch Dermatol. 2011;147(5):609-614. doi:10.1001/archdermatol.2011.89-a

A 16-year-old white boy presented with a 5-year history of hyperhidrosis and bilateral, white, “wrinkled” central palms made worse with exposure to water. The patient reported these changes only on the palmar aspects of the hands without involvement of the dorsal or the plantar surfaces. The patient stated that his hands were usually sweaty but denied other accompanying symptoms. The patient had no medical history and was taking no medications. There was no family history of similar symptoms, and findings from a review of systems were unremarkable.
