Telangiectasias are small blood vessels on the skin. They are usually meaningless, but may be associated with several diseases.
Alternative NamesVascular ectasias
ConsiderationsTelangiectasias may develop anywhere within the body but can be easily seen in the skin, mucous membranes, and whites of the eyes. Usually, they do not cause symptoms. However, some telangiectasias bleed and cause significant problems. Telangiectasias may also occur in the brain and cause major problems from bleeding.
Common CausesCauses may include:
- Alcohol use
- Aging
- Sun exposure
Diseases associated with this condition include:
- Ataxia - telangiectasia
- Bloom syndrome
- Cutis marmorata telangiectatica congenita
- Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome)
- Klippel-Trenaunay-Weber syndrome
- Nevus flammeussuch as port-wine stain
- Spider angioma
- Sturge-Weber disease
- Xeroderma pigmentosa
Call your health care provider if you notice enlarged vessels in the skin, mucous membranes, or eyes.
What to expect at your health care provider's officeThe doctor will perform a physical exam and ask questions about the symptoms, including:
- Where are the blood vessels located?
- Do they bleed easily and without reason?
- What other symptoms are present?
Tests may be needed to diagnose or rule out a medical condition. Such tests may include:
What else can I help you with?
Is Telangiectasia contagious?
no
How is ataxia-telangiectasia diagnosed?
Diagnosis relies on recognizing the hallmarks of A-T: progressive ataxia and telangiectasia. However, this may be difficult as ataxia symptoms do appear prior to telangiectasia symptoms by several years
What is ataxia-telangiectasia?
Ataxia-telangiectasia (A-T) is a rare, genetic neurological disorder that progressively affects various systems in the body.
What is capillary telangiectasia?
Capillary telangiectasia is a rare condition where tiny dilated blood vessels (capillaries) are present in the brain or spinal cord. These abnormal blood vessels can cause neurological symptoms such as headaches, seizures, or weakness, and may increase the risk of bleeding in the affected area. Treatment options depend on the location and symptoms of the telangiectasia.
What kind of skin lesion is a telangiectasia?
Small, dilated blood vessels that appear close to the surface of the skin. Telangiectasia is often a symptom of such diseases as rosacea or scleroderma.
What is hereditary hemorrhagic telangiectasia?
an inherited condition characterized by abnormal blood vessels which are delicate and prone to bleeding. Hereditary hemorrhagic telangiectasia is also known as Rendu-Osler-Weber disease.
What is the medical term meaning dilated superficial blood vessel?
telangiectasia
What Genetic disorder is Ataxia-telangiectasia?
It's a rare neurological disorder.
Where does the name ataxia-telangiectasia come from?
The name is a combination of two recognized abnormalities: ataxia (lack of muscle control) and telangiectasia (abnormal dilatation of capillary vessels that often result in tumors and red skin lesions ).
What are the demographics of ataxia-telangiectasia?
Both males and females are equally affected by A-T.
What is A-T disorder?
Ataxia telangiectasia disorder (also referred to as Louis-Bar syndrome) is a rare, neurodegenerative, autosomal recessive disease causing severe disability. Ataxia refers to poor coordination and telangiectasia to small dilated blood vessels, both of which are hallmarks of the disease.
