ABSTRACT

Symmetrical interdigital hyperkeratosis is a rare clinical entity first described by Frei in 1923. It is characterized by localized hyperkeratosis of the interdigital spaces of the hands and feet. No occupational, traumatic or irritant factors have been discovered, and only a few cases have been reported to date. We herein report a case of symmetrical interdigital hyperkeratosis in a 26-year-old Korean man.
