• A close association was noted between palmoplantar keratoderma (PPK) and Charcot-Marie-Tooth disease (CMT) in nine members of a family in five generations. Clinical, genealogic, electroneurophysiologic, chromosome, urinary amino acid, and histopathologic studies were performed to define the two entities. Charco-Marie-Tooth disease occurred with advancing age in all of the members with PPK, but in none without PPK. Palmoplantar keratoderma and CMT appear to be genetically associated and transmitted as an autosomal dominant trait. This is the first report, to our knowledge, of an association between PPK and CMT.
