Stevens-Johnson syndrome and respiratory failure in a 9-year-old boy.

The etiology of respiratory failure associated with Stevens-Johnson syndrome may be multifactorial, including upper airway involvement, pneumothorax/pneumomediastinum, and direct involvement of the respiratory mucosa. Respiratory failure from direct involvement of the respiratory mucosa is relatively uncommon. We describe a 9-year-old boy who had respiratory failure associated with Mycoplasma pneumoniae-induced Stevens-Johnson syndrome. Bronchoscopic examination of the airways revealed sloughed mucosa, ulcerative lesions, and inspissated secretions indicative of lower airway involvement with Stevens-Johnson syndrome. Although the mainstay of therapy is supportive care with controlled ventilation, rigid bronchoscopy with bronchoalveolar lavage to clear the airways of the debris was an invaluable adjunct to this patient's care.
