Toxic Epidermal Necrolysis

Toxic epidermal necrolysis, also known as Lyell's syndrome, is a type of severe skin reaction that, together with Stevens-Johnson syndrome, forms a spectrum of disease, with toxic epidermal necrolysis being the more severe. Early symptoms include fever and flu-like symptoms, and a few days later the skin begins to blister and peel, forming painful raw areas that also typically involve mucous membranes such as the mouth. Complications include dehydration, sepsis, pneumonia, and multiple organ failure.
