Two unusual cases of toxic epidermal necrolysis.

Two cases of toxic epidermal necrolysis (TEN) are presented. A 27-year-old woman presented with peripherally located targetoid plaques, papules, blisters and lip erosions which began 9 days after 'recreational' use of 'speed' (dexamphetamine and ephedrine) consistent with erythema multiforme major. Three days later she developed widespread lesions with large areas of blistering affecting 40% of body surface area. The diagnosis was revised to TEN. Intravenous cyclosporin led to rapid prevention of new blister formation. A 71-year-old woman, 3 months after commencing amiodarone, developed extensive erythema, blistering and erosions affecting 50% of body surface area, with a maculopapular rash affecting the limbs and extremities consistent with a diagnosis of TEN. She developed septicaemia following bilateral pneumonia with pleural effusions and died 7 days after admission.
