Stevens-Johnson and toxic epidermal necrolysis overlap syndrome

Description

A severe reactive skin disorder with features of both toxic epidermal necrolysis and Stevens-Johnson syndrome. It is defined by the presence of mucosal involvement and between 10% and 30% body surface area detachment of skin. It may be regarded as an intermediate form of these two disorders and, as with them, it can in most cases be attributed to a drug.
