Types of Psoriasis


Your psoriasis may look like a few patches of dandruff-like scales. Or it may cover large areas and be itchy and painful. It will probably go through cycles—flaring up, and then quieting down. Understanding your psoriasis is important, because it’s a condition that will be with you for life.

Since there are several types of psoriasis, knowing which type you have can help you learn how to better treat it and live with it.

  • Plaque psoriasis. The most common type, it causes dry, red patches (also known as plaques) with silvery scales that typically appear on the scalp, elbows, chest, knees and lower back.
  • Guttate (guh-tate) psoriasis. This type primarily affects people younger than 30 and can be triggered by a bacterial infection (such as a strep throat) or by a cold, skin injury, or medication. It appears as small, drop-shaped sores on the trunk, limbs, and scalp.
  • Inverse psoriasis. Smooth, red patches may appear in skinfolds in the armpits, groin, under the breasts, and around the genitals in this type of psoriasis. Sweating and friction can make things worse.
  • Erthrodermic psoriasis. The least common type, this psoriasis can cover the entire body with a red, peeling rash that can itch and burn. It may be triggered by sunburn, corticosteroids (cortisone) or other medications, or by another type of psoriasis that is not well controlled.
  • Pustular psoriasis. With this type of psoriasis, white blister-like pustules are surrounded by red skin. It can occur anywhere, but most commonly on the hands or feet.
  • Psoriatic arthritis. In addition to inflamed, scaly skin, this type of psoriasis also produces swollen, painful joints. While not as crippling as other forms of arthritis, it still can cause joint damage.
