A spider angioma is a dilated, small capillary. This image displays a central blood vessel with many "legs" branching from the center typical of spider angioma. This spider angioma is seen on a background of sun damage on the cheek, with multiple small linear veins nearby. This flat spider angioma demonstrates why it is often called a "spider," with tiny blood vessels radiating out from a central larger blood vessel. As displayed in this image, an angioma can sometimes just look like a red bump, with subtle, tiny radiating blood vessels around it. This image displays a central large blood vessel with linear legs radiating outwards typical of spider angioma.
