Here you will find pictures of several conditions that affect the palms of adults, the grasping surface of the hands. We constantly use our palms to interact with the world around us, and they come into contact with many things that damage, irritate, or change the skin. Irritant contact dermatitis and allergic contact dermatitis are the result of touching chemicals or plants (eg, poison ivy). Bacteria and viruses can cause certain infections like cellulitis and warts, respectively. Calluses are simply a thickening of the skin due to heavy use. Psoriasis and dyshidrotic dermatitis are chronic conditions that can cause an itchy rash and scaling of the skin. Click the links below to learn more about these conditions and their treatments.
