Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), or Lyell syndrome, are rare, delayed-type hypersensitivity reactions associated with high levels of morbidity and mortality.
The clinical hallmark of SJS and TEN is epidermal and mucosal detachment and necrosis.
The 2 entities are defined by the body surface area (BSA) of detachable or detached skin:
- < 10% of the BSA affected in SJS,
- 10% to 30% in overlap syndrome, and
- > 30% in TEN.
Current clinical practices, including the use of systemic agents, such as cyclosporine, systemic glucocorticoids, intravenous immunoglobulins (IVIGs), and antitumor necrosis factor (TNF) agents, are based only on retrospective case reports of series and empirical experience.
The association of these agents with the outcome, however, has not been proven in prospective trials.
The distribution of General Culprit Drugs & Treatments is illustrated in the figures.
