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.
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:

Factors that increase your risk for telangiectasias are based on the underlying condition.
This condition usually does not cause symptoms.
Signs of telangiectasias may include:
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.
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.
