Types of Psoriasis

Plaque psoriasis. About 80% of people with psoriasis have this. It causes the raised red patches with white scales.

Guttate psoriasis. Children, teenagers, and young adults are most likely to get this. It often appears after an infection, such as strep throat. It causes red, scaly, raindrop-shaped spots, usually on the belly, arms, legs, and scalp. It often clears up on its own without treatment.

Pustular psoriasis. Pus-filled blisters on hands and feet are the hallmarks of this type of psoriasis. The blisters usually dry up, turn brown, become scaly, and peel off.

Erythrodermic psoriasis. This causes fierce red and scaly skin over large areas of your body. It can develop from other forms of psoriasis. Psoriasis treatments or withdrawal from certain drugs, like corticosteroids, can trigger it.

Inverse psoriasis. You get scaly and bright red patches in the folds of your skin -- for instance, under your breasts, in your armpits, or on your genitals. Obesity can make it worse.

How Psoriasis Changes

Psoriasis symptoms come and go. You may only have minor symptoms once in a while. Or you may have severe symptoms most of the time. Certain things, like dry weather or stress, can cause them to flare up.

Though it's rare, very severe psoriasis can be dangerous. You need to see your doctor right away if your psoriasis spreads to cover large parts of your body or if you show signs of infection, such as fever.

To manage your psoriasis, work closely with your doctor and get support from your family and friends.
