Benign blood vessel: A spider angioma, or a spider nevus or telangiectasia, is a tiny dilated bllod vessel that is found just under the skin surface. They often have a central red spot and reddish extensions which spread out like a spider's legs or a web. They are common and are always benign. They can appear in women during pregnancy. If you have more than five spider angiomas, it can be a sign of liver disease.

See below: They are a type of telangiectasia (small dilated blood vessels) found just beneath the skin surface often having a central red spot with reddish extension which radiate outward like a spider's web. They are only found in the upper parts of the body and are caused by failure of a muscle which surrounds a cutaneous arterioles to close which, in turn, is due to increased estrogen levels.
