Palmoplantar keratoderma


Overview

Palmoplantar keratoderma (PPK) is a group of conditions characterized by thickening of the palms and soles of the feet. PPK can also be an associated feature of different syndromes.[1] In rare forms of palmoplantar keratoderma, other organs in the body may be affected in addition to the skin. PPK can either be inherited or acquired. Acquired palmoplantar keratodermas may arise as a result of infections, internal disease or cancer, inflammatory skin conditions, or medications.[2] The hereditary palmoplantar keratodermas are caused by a gene abnormality that results in abnormal skin protein (keratin). They can be inherited in an autosomal dominant or autosomal recessive patterns.[1][2]
