Lyell syndrome (toxic epidermal necrolysis or) is a dermatological condition induced potentially lethal and usually with a drug, causing an immune system response and misunderstood leading to necrosis of keratinocytes (skin cells) as a thermal burn or chemical. It is named after the Scottish dermatologist Alan Lyell (November 4, 1917 - November 2, 2007).
Lyell's syndrome is a disorder related to Stevens-Johnson syndrome and erythema multiforme. This is a bullous dermatosis defined by epidermal necrosis, reaching over 30. The drugs most often implicated are sulfa antibiotics, anticonvulsants and NSAIDs. And Nevirapine or Viramune (Antiretroviral). Lyell's syndrome is more common in women than in men. The higher incidence in the elderly is probably due to the greater number of drugs prescribed to them.
The diagnosis requires emergency hospitalization due to high mortality (20 to 70.
