Defining Erthrodermic Psoriasis

Erythrodermic psoriasis is described as a widespread reddening and scaling of the skin, often accompanied by itching or pain. Psoriasis characterized by severe redness and shedding of the body surface.

Erythrodermic Psoriasis is a generalized form of the disease, which covers 85% or more of the body, with which patients can be systemically ill. Erythrodermic psoriasis can appear suddenly or evolve from chronic Plaque Psoriasis, occasionally following initiation of exacerbating medications (such as Lithium or beta-blocking agents), or rapid systemic corticosteroid tapering.

Erythrodermic Psoriasis most commonly appears on people who have unstable Plaque Psoriasis, where the lesions are not clearly defined. The skin has large, red and fiery patches. Severe itching, swelling and pain may accompany the skin as it reddens and sheds.

Erythrodermic psoriasis can disrupt the body's ability to control its temperature, protein loss, and can lead to severe illness. In severe cases, people with this type of psoriasis may need to be hospitalized if they have lost a lot of fluid, have an infection or have poor blood flow (circulation). This can be life threatening.
