The most common benign vascular tumour are infantile haemangiomas. Those occur in the first few weeks of life and then show a characteristic pattern of growth and regression. Vascular malformations on the other hand are abnormal vessels in addition to the normal vascular system. They can occur in all systems, capillary, venous, arterial and lymphatic.
