What is it? Spider Angiomas sometimes called "spider telangiectasia" or "vascular spiders" are bright red small spots on the skin's surface. Sometimes described as looking like a "permanent zit" these red spots completely blanch under pressure. When examined closely a group of fine blood vessels can be seen on the skin's surface often arising from a larger vessel in the center.
What causes it? Spider Angiomas are caused by a dilation of a small blood vessel (capillary) near the surface of the skin. What causes this dilation is unknown. Spider Angiomas normally start at an early age and may regress with time. They are most commonly found in children and pregnant women. Located primarily on the face and neck and upper part of the body, they may also develop at sites of trauma.
Is it dangerous? Spider Angiomas are cosmetically annoying but completely harmless.
Can it be cured? Spider Angiomas can be treated effectively with laser therapy or electro destruction. Occasionally they reoccur after treatment.
Will it spread? Spider Angiomas do not spread, but it is common to have more than one.
Is it contagious? Spider Angiomas are not contagious and you cannot "catch them" from anyone.
