Acute epidermal necrolysis or Lyell syndrome.
Acute epidermal necrolysis may be caused by staphylococcal toxins (staphylococcal scalded skin syndrome and toxic shock syndrome) or may be related to usually drug-induced hyper-sensitivity mechanisms (toxic epidermal necrolysis). Diagnostic certainty can only be obtained by histologic localisation of a cleavage plane which is intraepidermal in staphylococcal scalded skin syndrome but situated at the dermo-epidermal junction in toxic epidermal necrolysis. Steroid therapy is indicated in toxic epidermal syndrome. This report of two cases of acute epidermal necrolysis emphasizes the importance of an early skin biopsy for accurate diagnosis and appropriate treatment.
