Airway, vision, bleeding or heart failure threat
Stridor, respiratory effort, feeding failure, rapidly closing visual axis, painful ulcer with infection, uncontrollable haemorrhage, a warm pulsatile expanding lesion or tachycardia and hepatomegaly can signal airway haemangioma, visual deprivation, AV shunting or major complication.
Action: Arrange same-day paediatric, dermatology and site-specific specialist care, stabilise airway and circulation, apply gentle direct pressure to bleeding and avoid blind incision or biopsy of a suspected high-flow malformation; urgent imaging and treatment proceed through a vascular-anomalies team.
Synopsis
Distinguish a proliferating infantile vascular tumour from a congenital vascular malformation, identify site- and syndrome-specific threats early, and coordinate propranolol, imaging and anomaly-directed intervention safely.
Infantile haemangioma is usually absent or faint at birth, becomes evident in the first weeks, proliferates rapidly during early infancy and then involutes over years.
Vascular malformations are structural channel abnormalities present at birth, although sometimes subtle; they grow with the child, expand with hormonal or traumatic change and do not follow spontaneous tumour involution.
Superficial infantile haemangioma is bright red and raised, deep disease is skin-coloured or blue and compressible, and mixed lesions show both levels across every skin tone.
Key red flags
Stridor, eye occlusion, ulceration, severe pain, poor feeding, failure to thrive, recurrent bleeding, palpable thrill, bruit, limb overgrowth, neurological signs, five or more cutaneous haemangiomas or a large segmental facial or lumbosacral lesion requires expedited specialist assessment.
High-flow malformation
Warmth, pulsation, bruit, thrill, rapid expansion, pain or bleeding indicates arteriovenous shunting and makes unplanned biopsy hazardous.

Birth and growth chronologyFirst step
Distinguish infantile tumour proliferation from a malformation or congenital tumour.
Management branches
First classification sequenceUse the timeline before the colour
An infant or child presents with a vascular-appearing birthmark or swelling.
Establish presence and completion at birth, postnatal onset, speed and trigger-related expansion using dated photographs and pregnancy and birth history.
Examine surface, depth, compressibility, warmth, pulse and bruit and assess vision, airway, feeding, hearing, ulceration, bleeding, pain and limb growth.
First-line low-risk careObserve actively through the growth window
A small uncomplicated infantile haemangioma is away from functional and high-distortion sites.
Key medicines
Propranolol oral solution for infantile haemangiomaFor eligible infants, start 0.5 mg/kg per dose twice daily in week 1, increase to 1 mg/kg per dose twice daily in week 2, then 1.5 mg/kg per dose twice daily from week 3, at least 9 hours apart, usually for 6 months under specialist care.
