A spider angioma is a group of tiny, dilated blood vessels.  It is often seen in children over two years old.  It is named because of how it looks. The round, dark red center of it looks like the body of a spider.  The fine blood vessels spread out from the center and look like the legs of a spider.  Spider angiomas often appear on the face, neck, hands or arms.  They are not present at birth.  There may be one or more on a child.  It is benign, which means it is not cancer. They do not lead to cancer. They rarely bleed.

The exact cause is not known.  It may be caused by an injury to the skin, such as a small scratch or insect bite or it may appear on its own.

Treatment is a cosmetic procedure and is not covered by insurance.
