Lyell's Syndrome and Antimalarials: A Case Report and Clinical Review.

Toxic epidermal necrolysis (TEN) or Lyell's syndrome is a rare, however, life-threatening mucocutaneous disorder with an epidermal detachment of a total body surface area (TBSA) of >30%. It is triggered by an idiosyncratic immune-allergic reaction to a drug, with many possible drugs implicated. Treatment success relies on early diagnosis and withdrawal of suspected/causative drug(s) and supportive care. Clinical evidence for specific therapies is still sparse. It is described a case of Lyell syndrome by sulfonamides for chemoprophylaxis of malaria. The patient presented with an extensive, rapidly evolving skin detachment, which progressed, despite supportive therapy, involving about 80% of TBSA. This led us to initiate a course of immunoglobulin with good clinical response. The aim of this work is to provide a discussion of the case and simultaneously make a practical literature review of TEN.
