Erythroderma: A Rare Complication of Dyshidrotic Eczema

Abstract

A 47-year-old man with a history of dyshidrotic eczema presented to the emergency department with diffuse erythema, chills and pruritus of three weeks' duration. The patient had received two injections of methotrexate in the preceding two weeks, both of which had failed to improve his whole-body erythema and pruritus. In the emergency department, the patient was evaluated for infection and admitted for the dermatology consultation. After being seen on the general medical floor by the dermatology service the diagnosis of erythroderma was made and the patient was treated with intravenous (IV) cyclosporine therapy, with which his rash dramatically improved over three days. This case report summarizes the presentation and differential of erythroderma, and highlights the importance of having a high index of suspicion for this potentially fatal disease.
