An atypical presentation of toxic epidermal necrolysis without mucosal involvement.

Toxic epidermal necrolysis (TEN) is a severe adverse cutaneous drug reaction with ubiquitous involvement of mucosa. Drugs are identified as the main etiology in most cases. Cutaneous involvement in TEN occurs in the form of widespread painful erythematous macules, targetoid lesions, full-thickness or focal epidermal necrosis, whereas mucosal involvement involves oral, genital, and ocular mucous membranes along with preceding prodromal flu-like symptoms. Atypical presentations include involvement of only mucosa without involvement of skin. We report a rare case of TEN without any mucosal involvement.
