Psoriatic erythroderma

Psoriatic erythroderma is a severe form of psoriasis that affects most of the body's surface. It is characterized by widespread, fiery redness and exfoliation of the skin. The condition can be life-threatening, especially in the elderly.

Symptoms

Psoriatic erythroderma typically involves more than 90% of the body's surface. Symptoms include intense and widespread redness of the skin, severe itching and pain, and the shedding of scales in sheets, rather than smaller flakes. Other symptoms can include fever, chills, and changes in the heart rate.

Causes

Psoriatic erythroderma can be triggered by a variety of factors, including abrupt withdrawal of systemic treatment, severe sunburn, or the use of certain medications such as lithium, anti-malarial drugs, and strong coal tar products. In some cases, the cause is unknown.

Diagnosis

Diagnosis is based on the clinical presentation of the disease. A skin biopsy may be performed to confirm the diagnosis and to rule out other conditions.

Treatment

Treatment typically involves hospitalization, especially for elderly patients or those with significant comorbidities. Systemic treatments, such as retinoids, methotrexate, or cyclosporine, are commonly used. Topical treatments, such as moisturizers and emollients, can help to soothe the skin and reduce scaling.

Prognosis

The prognosis for psoriatic erythroderma is variable. Some patients may experience a single episode and then return to a more typical form of psoriasis, while others may have repeated episodes. The condition can be life-threatening, especially in the elderly or those with significant comorbidities.
