Telangiectasia

  • Definition

    Telangiectasias are small blood vessels just below the surface of the skin. The blood vessels are very visible through the skin. They may appear as a single vessel or as many vessels in clusters.
  • Causes

    Telangiectasias are caused by blood vessels that are stuck in a wide open position. There is no clear reason for why this happens in many cases.
    Some telangiectasias are due to conditions like:

  • Risk Factors

    Factors that increase your risk for telangiectasias are based on the underlying condition.
  • Symptoms

    This condition usually does not cause symptoms.
    Signs of telangiectasias may include:
    • Red patches of skin that have a lacy pattern
    • Patches of red skin that turn white when pressure is applied, then red again after pressure is removed
  • Diagnosis

    Your doctor will ask about your symptoms and medical history. A physical exam will be done.
    Depending on the cause of the lesion, your doctor may take a biopsy of the area. You may be referred to a skin specialist.
  • Treatment

    Talk with your doctor about the best treatment plan for you. Often, treatment is not needed for the telangiectasias itself. Treatment depends on what is causing the telangiectasias.
    Make-up can be used to cover the red patches. Depending on the type of telangiectasia, laser therapy may be used to destroy the vessels.
  • Prevention

    There is no current guidelines to prevent telangiectasias.
