The patient was an eight-month-old girl. At first, cough and hoarseness appeared. Inspiratory stridor began within two days and the next day, a barky cough was noticed. Laryngeal fiberscopy showed that the subglottic epithelium was reddish and swellen. She was treated with antibiotics: intravenous steroid and epinephrine-steroid inhalation and an O2 nebulizer (humidifier). Next day, these symptoms improved. Although hoarseness remained, subglottic epithelium swelling and redness were reduced. On the sixth day (hospitalization), the patient was discharged.
