Subglottic haemangiomas are rare but have the potential to cause life-threatening complications. Affected infants are usually asymptomatic at birth but present with symptoms of a fixed upper airway obstruction as the lesion grows.1
Fifty per cent of infants with subglottic haemangiomas have cutaneous haemangiomas on the face.1
Bronchoscopy is necessary to make the diagnosis. Traditionally, steroids have been used to shrink lesions.1
However, propranolol has recently been shown to dramatically reduce the size of haemangiomas and should now be considered in proven cases.2,3
Clinicians need to be wary of diagnosing croup in infants under the age of 6 months especially if stridor is biphasic and cutaneous haemangioma is present.
