Spider Angioma

Spider angiomas (nevus araneus) are small, bright red spots that are surrounded by tiny blood vessels (capillaries), which resemble spider legs. After releasing pressure sufficient to blanch them, they refill from the central area. They are normal in many healthy people. They commonly develop in women who are pregnant or use oral contraceptives and in people who have cirrhosis of the liver.
