Subglottic hemangioma is a common cause of biphasic stridor in infants under 6 months. Which cutaneous finding strongly suggests the diagnosis before endoscopy?
- A Strawberry hemangioma (infantile hemangioma) on the face or neck in the 'beard distribution' ✓
- B Port wine stain over the trigeminal distribution
- C Ash leaf macules on the trunk
- D Multiple café-au-lait spots
Correct answer: A. Strawberry hemangioma (infantile hemangioma) on the face or neck in the 'beard distribution'
Explanation
Infantile hemangiomas in the 'beard distribution' (preauricular, mandibular, chin, neck, lower lip) are associated with subglottic airway hemangioma in up to 50% of cases. The segmental distribution pattern (PHACE syndrome) is particularly strongly associated. Infants with biphasic stridor and such cutaneous hemangiomas should undergo laryngoscopy. Port wine stains are associated with Sturge-Weber syndrome; ash leaf macules with tuberous sclerosis; café-au-lait spots with neurofibromatosis.
