Telangiectasias are small blood vessels that sit near the skin’s surface and widen and create visible patterns of lines. People often refer to them as spider veins. Telangiectasias may occur anywhere on the body or face.
For most people, telangiectasias neither cause any damage to overall health nor require treatment.
However, they can sometimes indicate a more severe medical condition and may warrant closer inspection.
This article looks at the causes, symptoms, diagnosis, and treatment of telangiectasia, as well as the outlook.
Telangiectasias can occur anywhere on the body but are most noticeable on the skin, the mucous membranes, and the whites of the eyes.
The exact cause of telangiectasias is
- sun and wind exposure
- medications that widen blood vessels
- excessive alcohol consumption
- trauma to the skin
- surgical incisions
- prolonged use of oral or topical corticosteroids
In most cases, telangiectasias do not cause any symptoms. However, they can sometimes bleed. If this bleeding occurs in or near the brain, it can have severe effects.
Unless a more serious medical condition is causing telangiectasias to occur, they are not a reason for concern.
People have a
The growth of the body to accommodate a developing fetus places significant pressure on the blood vessels.
Telangiectasia is sometimes a symptom of a more severe medical condition, such as:
- Ataxia-telangiectasia: This inherited childhood disease affects the brain and other body parts.
- Bloom syndrome: This is a rare genetic disorder that causes various symptoms, including telangiectasias.
- Osler-Weber-Rendu syndrome: Also known as hereditary hemorrhagic telangiectasia, this is a genetic condition that can affect blood vessels in the skin and throughout the body and lead to bleeding.
- Port-wine stain: This is a vascular birthmark that presents as a large patch of discolored skin.
- Klippel-Trenaunay-Weber syndrome: This is a combination of port-wine stain, varicose veins, and soft tissue enlargement.
- Rosacea: Rosacea is a chronic skin condition that causes skin discoloration and inflammation in the face.
- Spider angioma: This is an abnormal collection of blood vessels near the skin’s surface.
- Sturge-Weber syndrome: This is a rare disorder that can affect the nervous system.
- Xeroderma pigmentosum: In people with this rare medical condition, the skin and eyes become very sensitive to ultraviolet (UV) light.
Connective tissue diseases
Telangiectasias may also develop on the face and on the hands and feet where the skin meets the nail. Sometimes, this may be the result of a connective tissue disease.
Examples of connective tissue diseases include:
- Systemic scleroderma: Systemic scleroderma is the rapid growth of connective tissue in the skin and other organs. People with systemic scleroderma
may experiencetelangiectasias on and around their faces.
- Dermatomyositis: This condition can cause rashes across a person’s shoulders, back, knuckles, and palms. These rashes may include telangiectasias.
- Lupus: People with lupus may get telangiectasias in the nail folds and on the edges of discoid lupus lesions.
Telangiectasias are fine, threadlike lines that may appear blue, red, or purple. The color of these lines will depend on whether they are veins or arteries.
The distorted blood vessels generally measure between
They commonly occur on the face, nose, chin, and cheeks, where they may cause facial redness.
Telangiectasias also often appear on the legs, chest, back, and arms. People often refer to those that appear on the legs as spider veins. Spider telangiectasia is telangiectasia that has a red central feeding vessel with outward branches.
Telangiectasias are typically not a cause for concern. However, a doctor can assess the markings and determine whether they indicate a more serious condition.
For example, small lesions on the lips, nose, and face could be a sign of hereditary hemorrhagic telangiectasia, a potentially serious condition.
Furthermore, limited patches over the breasts, buttocks, and joint folds
People should also seek treatment as soon as possible if they become aware of a family history of telangiectasia or have any bleeding or lesions in their mouth or eye area.
These symptoms could indicate a more serious condition. To determine whether they have an underlying medical condition, an individual may need some of the following tests:
There is no cure for telangiectasia, but it is
If acne or rosacea is the underlying cause, a doctor may prescribe an oral or topical antibiotic.
Many people choose to remove telangiectasias for cosmetic reasons and because the condition can cause discomfort.
Laser therapy is minimally invasive and is typically the most straightforward treatment for facial telangiectasia and broken capillaries. Laser ablation can seal the widened blood vessels. This procedure does not cause much pain, and the recovery time is short.
It is a minimally invasive procedure in which a dermatologist
This treatment does not usually require a stay in the hospital, as there is no recovery time or anesthesia. It may also be a good option for facial telangiectasias. People often require repeat treatments.
Some causes of telangiectasia will not resolve. However, treatment can help remove any new telangiectasias that occur.
There are several treatment options for telangiectasias.
Individuals can usually resume their regular activities after treatment, but they should protect the treated areas from sunlight until they are fully healed.
If blistering, crusting, or scabbing occurs, it is best to clean the skin gently and apply an antiseptic ointment. A doctor may prescribe an antibiotic, but nonprescription antibacterial options can also be beneficial.
A doctor will need to monitor a person who has telangiectasias as a result of an underlying health condition.
Telangiectasias are small blood vessels that widen and become visible near the skin’s surface.
Although they are generally harmless and asymptomatic, they can occasionally lead to pain and itching, and some people may want to remove them for cosmetic reasons.
Occasionally, telangiectasia may be a symptom of a more severe medical condition that requires treatment.
