Telangiectasias are abnormally dilated blood vessels associated with a number of diseases.
Telangiectasias may develop anywhere within the body but can be easily seen in the skin, mucous membranes, and whites of the eyes. Though most are asymptomatic, some telangiectasias bleed readily and cause significant problems. Telangiectasias may also occur in the brain and cause significant problems from bleeding.

What to expect at your health care provider’s office
Telangiectasia can be a symptom of a disease. Most of those disorders can be diagnosed by history and physical examination.
Medical history questions documenting telangiectasia in detail may include:
- Is the condition visible?
- Where is it located exactly?
- Do the vessels bleed easily? o Do they bleed spontaneously?
- What other symptoms are also present?
Physical examination is usually limited to a dermatologic examination.
Various X-rays, CT scans or MRI scans, and liver function studies, or other blood studies may be indicated. The specific tests will depend on the suspected disease.
