Yesterday, I got up and began to look like a palm in my abdomen, which is still a little red, with a little swelling and pain from time to time, and a little black in my ankle. I learned some knowledge about spider nevus from the doctor. Today, I'd like to learn from you where spider nevus doesn't appear.

Spider mole does not appear in which part

First, the size of spider nevus is different, the central nevus is protruding on the skin, the pulsation can be seen by slide pressing, and the capillary dilation around the nevus can be seen by naked eye, which is arranged radially. 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.

Second: spider nevus shape like spiders, nevus body next to the radial arrangement of telangiectasia. Spider nevus is a warning light of liver failure, because spider nevus is common in acute, chronic hepatitis or cirrhosis. The size of spider nevus is different, and the diameter of the larger one can reach 1.5cm. The central nevus is protruding on the skin. The pulsation can be seen on the slide. The capillary dilatation around the nevus can be seen by naked eye.

Third: the nevus is named after its spider like shape. It is composed of silk like arteries and blood vessels arranged radially from the central point 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.
