title: The palmoplantar keratodermas: much more than palms and soles.
abstract: The inherited palmoplantar keratodermas (PPKs) are a diverse and often clinically confusing branch of the genetic skin diseases. As the name suggests, the lesions of PPK primarily affect the palms and soles of the feet, although a number of the PPKs are also associated with a genetic predisposition to other conditions, including cancer, hearing loss and heart failure. The mapping and identification of genes that underlie the PPKs reveal new insights into the biological interactions of the structural components of the palmoplantar epidermis and further our understanding of epidermal disease. More significantly, by genetically characterizing the PPKs, genes that have a role in life-threatening disorders might also be identified.
