A venous malformation can occur anywhere in the body and may be deep or superficial, localized or diffused. The jaw, cheek, tongue, lips, and extremities are common sites for a venous malformation. These lesions are soft to the touch, the color disappears and empties as the lesion is compressed. They may be painful, bleed easily, cause difficulty in wearing shoes or cloths, and may be cosmetically unpleasing.
There are various genetic components and some syndromes that include vascular malformations.
Treatment of malformations may include embolization, surgical removal, or a combination of the two. Embolization involves the injection of a sclerosing agent into the abnormal blood vessels, causing them to involute.
