Vascular tumours



Vascular anomalies can be classified in two different classifications: malformations or tumours. They are often confused, especially at the time of diagnosis.

Vascular malformations occur because of an error in the development of vascular embryogenic tissue, meaning amongst other things, that they are present at the time of birth. Vascular tumours appear after the birth of the patient (except congenital hemangiomas), a period that can vary from a few weeks to several months or many years.

Here, we will describe tumours and malformations as different entities, focusing our attention on vascular tumours.



This material of vasculopathies covers the basics about PI3K related overgrowth syndromes, Proteus syndrome, Parkes-Weber syndrome and Sturge-Weber syndrome, what happens in children and what it is known until now. This material is in constant evolution and further revisions will be done once per year. If you have information to add to the content, please, send us an email to
