A venous malformation is a relatively common vascular birthmark. Because of the venous blood vessels, these lesions most often have a purple or blue hue. They are soft and compressible, and often get larger and deeper in color when gravity allows for blood to pool in the aberrant vessels. Although venous malformations may be largely asymptomatic, they can be tender when engorged with excess blood or with gradual enlargement. The slow-flow nature of these malformations sometimes leads to clot formation (thrombosis) within the malformation; these may subsequently lead to firm, calcified phleboliths.
