Stevens-Johnson syndrome (SJS) is an immune-complex-mediated hypersensitivity disorder. Stevens-Johnson syndrome ranges from mild skin and mucous membrane lesions to a severe, sometimes fatal systemic illness, toxic epidermal necrolysis (TEN). Stevens-Johnson syndrome and toxic epidermal necrolysis are characterised by detachment of the epidermis and mucous membrane. They are mainly, but not always, caused by drugs.
