About this condition
Vascular malformations are congenital differences in blood or lymphatic vessels. They may be visible as a coloured patch or a soft deeper swelling and can affect different body areas. The type cannot be established from colour alone.
What matters most
Capillary, venous, lymphatic, arterial and combined malformations behave differently. Some are present at birth but become more apparent as a child grows. Their assessment differs from that of an infantile haemangioma, which is a vascular tumour with a characteristic growth phase.
Symptoms and reasons to seek care
A pink or purple flat mark, bluish compressible swelling or an area that changes with position may be noticed. Lesions on a hand, digit or near a joint can cause discomfort or functional restriction. Bleeding and rapid changes require particular attention.
How it differs from similar conditions
Vascular malformations are not all haemangiomas and not all ordinary skin birthmarks. The correct category matters because treatment methods differ. Avoid attempted puncture, cautery or massage of an unexplained vascular lesion.
Assessment and diagnosis
A clinician documents onset, growth, size, warmth, colour and any limitation of movement. Doppler ultrasound, MRI or specialist consultation may be selected based on the suspected malformation; every child does not need the same set of tests.
Monitoring and treatment
Management ranges from observation to specialised care in a vascular anomaly team. Laser therapy, sclerotherapy or surgery are considered only for certain types and indications. A general vascular procedure listed elsewhere on the site does not confirm paediatric malformation treatment at MZ.
When emergency help is needed
Uncontrolled bleeding, rapidly increasing swelling with severe pain, impaired limb circulation, or difficulty breathing requires emergency assessment. Do not puncture or burn the lesion; call 103 or 112 if there is acute danger.

Frequently asked questions
Is a vascular malformation the same as a haemangioma?
No. They are different categories of vascular anomalies with different natural histories and care needs.
Does every child need an MRI?
No. Imaging is selected according to the lesion’s type, size, depth and symptoms.
Can a coloured birthmark be treated at home?
Do not pierce, burn or attempt to remove an unexplained vascular lesion; treatment requires accurate diagnosis.
