Erythrodermic psoriasis after discontinuation of ixekizumab

INTRODUCTION Erythroderma is defined as generalized redness and scaling affecting more than 90% of the skin surface and often accompanied by systemic complications such as hypothermia, dehydration, and electrolyte imbalance. Treatment is targeted at the underlying cause, and preexisting dermatoses are identified in 65% of patients. Psoriasis is the most common underlying disease in erythrodermic adults, accounting for almost half of cases, and can be triggered by withdrawal of medications, infection, or irritant contact dermatitis.
