Common manifestations: reddish or purplish marks on the skin, dilated and visible veins, and a difference in size or length in one arm or leg compared to the opposite side.

When to seek evaluation? In the presence of extensive vascular marks or notable asymmetry of a limb in childhood, a targeted evaluation is advisable to understand its extent.

Which specialists are involved? the angiologist and the vascular surgeon assess the blood vessels, the pediatrician supports the child's development, and the internist coordinates the general aspects. Bringing these professionals together facilitates an organized follow-up of the manifestations over time.
