Are there other types of psoriasis?

The most common type of psoriasis is called plaque psoriasis. However, there are other types of psoriasis that others may experience.

Guttate psoriasis, which affects approximately 2% of people with psoriasis, is characterized by small (3–5 mm) confetti-like red, scaly patches. A common cause is an acute infection such as strep throat.^[1]

Erythrodermic psoriasis is a life-threatening form of psoriasis which presents as red, peeling skin that covers nearly the entire body. As a result, people will experience severe electrolyte imbalances, fluid loss, low body temperature, and severe skin shedding. If untreated, this can lead to shock (decreased blood flow which can result in organ failure) or life-threatening infection.^[2]

Pustular psoriasis causes pus filled blisters on the hands, feet, or all over the body. This form of psoriasis can be caused by a multitude of factors including genetics, stopping steroid medications too quickly, pregnancy, or infection.^[1]
