The site of spider nevus

First, the appearance of spider nevus is due to the decrease of the inactivation ability of estrogen when the liver has pathological changes. As a result, a large amount of estrogen accumulates in the body, causing the expansion of small arteries in the body. Go to the hospital to check liver function.

Second, the nevus is named after its spider like shape. It is composed of silk like arteries and blood vessels arranged radially from the center to the surrounding. The larger one can see or touch the pulsation. If the center is pressed lightly with a glass slide or cotton swab, the nevus will turn white or disappear. After removing the pressure, the blood can be seen to fill from the center to the surrounding and quickly return to red. The nevus is mainly distributed in the area where the vena cava flows through, more in the face and neck , chest and breast above, as well as arms, fingers, etc. The causes of liver palms and spider nevi in patients with liver diseases are basically the same. They are all caused by the dysfunction of liver function, unable to deal with estrogen, resulting in excessive estrogen acting on the arterioles and causing them to expand.

Third: spider nevus of different sizes, the central nevus body protuberant skin, slide pressure can be seen beating, naked eye can be seen around the nevus telangiectasia, radial arrangement. It mainly occurs in the parts above the trunk, especially in the face, neck and hand, and can also occur in the injured parts. It is usually unilateral, single or multiple. Multiple cases should be suspected of liver disease, and similar lesions may occur in the lip and nasal mucosa.

Do not remove it by hand. Otherwise, the pigmentation is serious and the scar is easy to be left. It is recommended to go to a regular 3A hospital for treatment.
