Stridor is not always croup.

Respiratory distress and stridor are common presenting symptoms for children in the emergency department. Most of these children will have common illnesses such as bronchiolitis or croup. Clinicians, however, must maintain a broad differential diagnosis and a healthy skepticism in the approach to each child's case so as not to miss uncommon or atypical presentations. We describe the case of a child with stridor in whom an airway hemangioma was ultimately diagnosed.
