Definition of Spider angioma:

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

Causes, incidence, and risk factors:

Spider angiomas are very common. They are especially common during pregnancy and in patients with liver disease. They occur in both children and adults.

Symptoms:

• Blood vessel sore (lesion)
  • May have a red dot in the center
  • Has reddish extensions that reach out from the center
  • Disappears with pressure and reappears when pressure is released
• Most often seen on the face and neck

Signs and tests:

No testing is usually necessary, but a skin biopsy may be needed to confirm the diagnosis in some cases. Blood tests may be done if a liver problem is suspected.

Treatment:

Treatment is generally not necessary. In some cases, electrocauterization or laser treatment may be used.

Expectations (prognosis):

Spider angiomas often disappear in children but tend to persist in adults.

Calling your health care provider:

A spider angioma can usually be examined during a routine visit with your health care provider. It is important to mention to your doctor if you develop a new spider angioma, to rule out related medical conditions.
