Plaque Psoriasis

Plaque psoriasis (also known as psoriasis vulgaris) is the most common type of psoriasis and is characterized by well defined red patches with dry, silvery scales on your scalp, elbows, knees, lower back and around the belly-button. Your face will not usually be involved. If the scales are picked off, small points of bleeding will typically occur. You may see thick areas of scaling on the palms of your hands and the soles of your feet; individual patches may last for months to years, and may come and go.
