Use of steroids for erythema multiforme in children.

QUESTION: I recently diagnosed an erythema multiforme rash in several patients, two of whom had the major variant, Stevens-Johnson syndrome. Should these patients be managed with corticosteroids? ANSWER: In most cases, mild erythema multiforme is self-limited and resolves in 2 to 4 weeks. Stevens-Johnson syndrome is a serious disease that involves the mucous membranes and lasts up to 6 weeks. There is no indication for using steroids for the mild form. Use of steroids for erythema multiforme major is debatable because no randomized studies clearly indicate which children will benefit from this treatment.
