	From Robbins Pathologic Basis of Disease, 5th Ed., p 1195.
	"Another variant {of erythema multiforme}, termed toxic epidermal 
necrolysis, results in diffuse necrosis and sloughing of cutaneous and 
mucosal epithelial surfaces, producing a clinical situation analagous to and 
extensive burn.
	MORPHOLOGY. Histologically, early leasions show a superficial perivascular, 
lymphocytic infiltrate associated with dermal edema and margination of 
lymphocytes along the dermoepidermal junction, wher they are intimately 
associated with degenerating and necrotic keratinocytes.  With time, there is 
upward migration of lymphocytes into the epidermis.  Discrete and confluent 
zones of epidermal necrosis occur with concomitant blister formation.  
Epidermal sloughing leads to shallow erosions." end citation

	Robbins also notes that erythema multiforme is a hypersensitivity response to 
certain infections and drugs, athough it does not list offenders, nor does it 
say what type of hypersensitivity reaction, although I would suspect type II 
or III.  I might suggest a dermatology text for more information.
