Spider nevi, also known as spider angiomas, are small, red, spider-shaped marks on the skin. They typically don't go away on their own.
Spider nevi are caused by dilated blood vessels, and while they are harmless, they can be a sign of underlying liver disease.
If you are concerned about a spider nevus, it is important to consult a doctor. They can determine the cause of the spider nevus and recommend treatment options.
Treatment options may include laser therapy, sclerotherapy, or electrocautery.
