Spider angiomas, also known as "nevus araneus," are a type of angioma found slightly below the skin's surface. They often contain a central red spot, and reddish extensions that radiate outward like a spider's web.

They are often associated with high estrogen levels, so they are commonly found on pregnant women.

• Liver disease.

People with impaired liver function may also exhibit spider angiomas, possibly because the liver is not processing excess estrogen properly.

Treatment

As with cherry angiomas, no treatment is medically necessary. Electrosurgery and laser treatments are effective on this type of angioma.
