Definition: Spider angiomas, or spiders, are blood vessels near the skin's surface that look like thin red lines extending from a central dot. Usually found on the face and neck, these marks might temporarily turn white when touched, or disappear completely. They are often seen in people with severe chronic liver disease, in children, and in women who are pregnant or on oral contraceptives.
Also Known As: Nevus araneus, spider nevus, vascular spider, spider telangiectasia
