Spider angioma

Nevus araneus; Spider veins

Spider angioma is an abnormal collection of blood vessels near the surface of the skin.

I Would Like to Learn About:

  • Causes

    Spider angiomas are very common. They often occur in pregnant women and in people with liver disease. They can appear in both children and adults.

  • Symptoms

    The main symptom is a blood vessel sore (lesion) that:

    • May have a red dot in the center
    • Has reddish extensions that reach out from the center
    • Disappears when pressed on and comes back when pressure is released
    • Is seen most often on the face and neck
  • Exams and Tests

    Most of the time you do not need tests to diagnose the condition. But sometimes a skin biopsy may be needed to confirm the diagnosis. Blood tests may be done if a liver problem is suspected.

  • Treatment

    Most of the time you do not need treatment, but burning (electrocautery) or laser treatment is sometimes done.

  • Outlook (Prognosis)

    Spider angiomas often disappear in children. They tend to last in adults.

  • When to Contact a Medical Professional

    Let your health care provider know if you have a new spider angioma so that other related medical conditions can be ruled out.
