In the overall picture of psoriasis, one cannot forget the least known type of psoriasis. Erythrodermic Psoriasis also known as “exfoliative” psoriasis, this is the least common type. It occurs in about 1% or 2% of people who develop psoriasis. Erythrodermic psoriasis can be life-threatening because the skin loses its protective functions. The skin may not be able to safeguard against heat and fluid loss nor prevent harmful bacteria and other substances from entering the body. Patients are usually hospitalized and given intravenous fluids. Body temperature regulation may be required.
Erythrodermic psoriasis may occur suddenly in a person who has never had psoriasis or evolve from plaque psoriasis. Triggers include infection, emotional stress, alcoholism, and certain medications such as lithium, anti-malarial drugs, and a strong coal tar preparation. It also may be triggered by excessive use of potent corticosteroids, which is why it is important to use corticosteroids as instructed. Suddenly stopping a psoriasis medication, such as cyclosporine or methotrexate, also can trigger erythrodermic psoriasis.How to recognize erythrodermic psoriasis:
Severe redness and shedding of the skin that covers a large portion of the body.
Skin looks as if it has been burned.
Fluctuating body temperature, especially on very hot or cold days.
Accelerated heart rate due to increased blood flow to the skin — can complicate heart disease and cause heart failure.
