Stevens-Johnson syndrome and toxic epidermal necrolysis: oncologic considerations.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe skin toxicities that may occur in patients with cancer. They are caused by infection or a drug reaction and can result in sepsis, severe ocular complications, and even death. Skin lesions usually are preceded by prodromal flulike symptoms. A rash with subsequent blistering and denudation follows. Diagnosis is made by skin biopsy, and classification is based on body surface area and visceral organ involvement. Because many of the drugs associated with SJS and TEN are used to treat cancer, early recognition and intervention are critical to achieving a favorable outcome. Interventions include stopping the suspected offending agent. The use of steroids is controversial. Healthcare professionals always should consider an early transfer to a burn unit for patients with a comorbid condition such as cancer because this action is associated with improved outcomes. Implications for oncology nurses and a case study are presented in this article.
