What is toxic epidermal neurolysis?

I am a medical student actually facinated by these kinds of conditions and toxic epidermal neurolysis though i haven't actually studied it sounds like a condition in which the epidermal lining around the brain sloughs away. Now i don't know if you meant toxic epidermal necrolysis, which is also a sloughing of the epidermal layer of the skin typically involving over 30% of the body as well as mucous membranes like your mouth and throat. it is very painful and gruesome almost exactly like 2nd degree burns. All said and done, if someone survives without infection, generally there isn't a lot of scaring or disfigurement. hope this helps
