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.

Signs and Symptoms
Spider angiomas are most often seen on the face or trunk, and they also may be seen on the hands, forearms, and ears. There may be one spider angioma or several. Each one is a small (1–10 mm) area of redness, which disappears with direct finger pressure but rapidly returns when the pressure is released. There is often a central red dot and small red lines radiating out from the center.
