Telangiectasias /tɛlˌæn.dʒiː.ɛkˈteɪ.zi.ə/ or angioectasias (also known as spider veins) are small dilated blood vessels near the surface of the skin or mucous membranes measuring between 0.5 and 1 millimeter in diameter. They can develop anywhere on the body but are commonly seen on the face around the nose cheeks and chin. They can also develop on the legs specifically on the upper thigh below the knee joint and around the ankles.
