Haemangioma
Overview
An infantile haemangioma is a benign growth of blood vessels that often appears during the first weeks of life. It may grow for several months before slowly fading.
Babies develop rapidly, and the same condition can look different from one child to another. This guide supports informed conversations with a health professional; it cannot diagnose a baby or replace individual care.
Signs and symptoms
It can look like a bright red raised mark or a deeper blue-purple swelling. Size, depth and location vary.
Parents know their baby best. A change in feeding, alertness, breathing, colour, temperature or wet nappies can be as important as one isolated sign, especially in the newborn period.
Causes
The cause is not fully understood. Prematurity, low birth weight and multiple pregnancy are associated with higher likelihood.
Risk factors
Risk depends on the condition. Prematurity, a difficult birth, infection exposure, feeding difficulties, family history or another medical condition may matter, but many affected babies have no obvious risk factor. Risk factors do not confirm a diagnosis.
Diagnosis
Most are diagnosed by appearance and growth pattern. Ultrasound or specialist review may be used for deep, multiple or atypical lesions.
A clinician may review pregnancy and birth history, feeding, growth and symptom timing before examining the baby. Tests are chosen only when the history or examination suggests they will help.
Treatment options
Small low-risk haemangiomas are observed. Treatment such as a beta blocker may be recommended for lesions threatening vision, breathing, feeding, skin integrity or disfigurement.
Medicines, specialised feeds, procedures or monitoring should be used only on advice from the baby’s healthcare team. Never give a newborn over-the-counter medicine unless a qualified professional has confirmed the product and dose.
Home care
Keep a simple record of feeds, wet and dirty nappies, sleep, temperature when advised, and changes in symptoms. Follow safer-sleep guidance, wash hands before baby care, attend follow-up appointments and ask for help if feeding is painful or ineffective.
Prevention
Not every condition can be prevented. Antenatal care, recommended newborn screening, smoke-free surroundings, good hand hygiene, safe preparation of feeds, scheduled immunisation and prompt assessment of an unwell baby can reduce avoidable harm.
Possible complications
Most mild newborn problems improve without lasting effects, while some conditions need prompt treatment to protect feeding, growth, breathing, hearing or development. The healthcare team can explain the outlook for the individual baby and arrange follow-up when needed.
When to seek urgent medical care
Urgent review is needed for breathing or feeding effects, eye involvement, rapid ulceration, significant bleeding or signs of heart strain with multiple large lesions.
Seek urgent help for a baby who is difficult to wake, unusually floppy, struggling to breathe, turning blue or very pale, having a seizure, repeatedly vomiting green fluid, feeding much less, or producing notably fewer wet nappies. A fever or abnormally low temperature in a young baby needs prompt professional advice.
Frequently asked questions
Is this my fault?
No. Newborn conditions usually arise from development, feeding, infection, birth-related factors or causes outside a parent’s control.
Can I continue feeding my baby?
Often yes, but the safest plan depends on the condition and how well the baby feeds. Ask promptly if feeds are tiring, painful, repeatedly vomited or much shorter than usual.
When should I arrange follow-up?
Use the timeframe given by the maternity, neonatal or primary-care team. Arrange an earlier review if symptoms worsen, feeding changes, growth is a concern or you remain worried.
Summary
Early risk assessment matters because selected haemangiomas benefit from treatment during their growth phase. Early assessment is especially important in young babies because they can become unwell quickly.
