One of the serious side effects to Tamiflu is skin reactions. Stevens-Johnson Syndrome, erythema multiforme and toxic epidermal necrolysis have all been reported in patients taking Tamiflu.

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

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are two forms of a life-threatening skin condition, in which cell death causes the epidermis to separate from the dermis.

Muscle tissue is deep to epidermal tissue. Epidermal tissue is superficial to muscle tissue.

An epidermal cell is a cell that is part of the outer layer of an organism. For example, in humans, skin cells are epidermal. Leaves on plants have epidermal layers on the top and bottom of the leaf.
