Palmoplantar keratoderma (PPK) is a group of inherited skin disorders characterized by thickening of the skin on the palms of the hands and the soles of the feet. It is a type of keratoderma that specifically affects these areas. The condition typically presents as thickened, dry, and calloused skin on the palms and soles, which may appear yellowish or brownish in color. The affected skin can be rough, cracked, and may cause discomfort or pain. In some cases, PPK may be associated with additional symptoms such as blistering, redness, or scaling.

This vignette is an excellent resource for residents preparing for OSCE-style examinations and can also be used as a self-directed learning tool for healthcare professionals seeking to enhance their knowledge and skills in managing keratoderma climactericum.
