Erythrodermic psoriasis

Erythrodermic psoriasis affects the entire skin surface. It is often seen in the elderly population, and may develop gradually as an extension of plaque psoriasis or erupt suddenly. The eruptive variant may be accompanied by widespread pustulation (generalised pustular psoriasis), fever and other systemic symptoms. Typical lesions of psoriasis may not be present. See here for photos of erythrodermic psoriasis.

Erythrodermic psoriasis can be difficult to treat—refer for hospital assessment and management by a dermatologist. Complications of erythroderma include heart failure, infection, gastrointestinal malabsorption and anaemia.
