TELANGIECTASIAS

Telangiectasias can occur anywhere on the skin but are most common on the face, chest, and hands. They generally develop by age 30 years and increase in number with age. Telangiectasias are bright red to purple and blanch with pressure. They can be visualized by transilluminating the patient’s fingers with a small bright flash-light. Mucosal telangiectasias can occur anywhere along the GI tract and are often visible on the lips and tongue. GI bleeding occurs in approximately one third of patients with HHT and is another common cause of iron deficiency anemia.

If you have telangiectasias, we suggest additional tests:

  • A blood test can check for anemia, or iron deficiency in the blood.
  • A CT scan can show internal AVMs, such as in the lungs, liver, and brain.
  • A gastrointestinal doctor can insert a small camera down your throat to check for AVMs in your esophagus.
  • An echocardiogram uses sound waves to check blood flow in and out of your heart.
