Learn About Palmoplantar Keratoderma

What is the definition of Palmoplantar Keratoderma?
Palmoplantar keratoderma (PPK) is a group of skin conditions characterized by thickening of the skin on the palms of the hands and soles of the feet. PPK can also be a feature of various underlying syndromes. In rare forms of PPK, organs other than the skin may also be affected. PPK can be either acquired during the lifetime (more commonly) or inherited. Acquired PPKs may arise due to changes in a person's health or environment. Inherited PPKs are caused by genetic changes that result in abnormalities of keratin, a skin protein. Depending on the genetic cause, inheritance can be autosomal dominant or autosomal recessive.
