Palmar-plantar psoriasis is a form of psoriasis that mainly affects the palms of the hands and the soles of the feet. It appears as thick red plaques, sometimes covered with scales, which can cause itching, pain and cracking. As with nail psoriasis, this type of psoriasis is often difficult to relieve because of the daily pressure exerted on the affected areas. Find out more information below.
