Infantile Stevens Johnson syndrome and toxic epidermal necrolysis: A systematic review of clinical features and outcomes in children ages 12 months and under.

Background/objectives: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening mucocutaneous hypersensitivity reactions that carry significant morbidity and mortality. While clinical features are well documented in adult and pediatric patients, infantile cases are rarely reported. Our objective was to synthesize clinical features and outcomes in this population.
