A 34-year-old man presented with red skin from his neck to his feet for the last month (Figure 156-1). He was having a lot of itching and his skin was shedding so that wherever he would sit, there would be a pile of skin that would remain. He denied fever and chills. He admitted to smoking and drinking heavily. The patient's vital signs were stable with normal blood pressure and he preferred not to be hospitalized. He had some nail pitting but no personal or family history of psoriasis. The presumed diagnosis was erythrodermic psoriasis but a punch biopsy was done to confirm this. A complete blood count (CBC) and chemistry panel were ordered in anticipation of the patient needing systemic medications. A purified protein derivative (PPD) was also placed. The patient was started on total body 0.1% triamcinolone under wet wrap overnight and given a follow-up appointment for the next day. The patient was also counseled to quit smoking and drinking. The following day his labs showed mild elevation in his liver function tests (LFTs) only. The following day his PPD was negative and he was already feeling a bit better from the topical triamcinolone. Cyclosporine was started and the patient improved rapidly.

Erythroderma is an uncommon condition that affects all age groups. It is characterized by a generalized erythematous rash with associated scaling. It is generally a manifestation of another underlying dermatosis or systemic disorder. It is associated with a range of morbidity, and can have life-threatening metabolic and cardiovascular complications. Therapy is usually focused on treating the underlying disease, as well as addressing the systemic complications.

- It affects all age groups, from infants to the elderly.
- In adults, the average age of onset is 41 to 61 years of age, with a male-to-female ratio of 2:1 to 4:1.1
- It accounts for approximately 1% of all dermatologic hospital admissions.2
- It can be a very serious condition resulting in metabolic, infectious, cardiorespiratory, and thermoregulatory complications.3

In almost 50% of cases, erythroderma occurs in the setting of a preexisting dermatosis; however, it may also occur secondary to underlying systemic disease, malignancy, and drug reactions. It is classified as idiopathic in 9% to 47% of cases.3

- The pathophysiology is not fully understood, but it is related to the pathophysiology of the underlying disease. However, the factors that promote the development of erythroderma are not well defined.
- The rapid maturation and migration of cells through the epidermal layer results in excessive scaling. The rapid turnover of the epidermis also results in fluid, electrolyte, and protein ...
