summary

In the human body's upper body skin surface sometimes appears, the shape looks like a small spider, the color dark red congestion spot is called spider nevus. It is a manifestation of radial expansion and hyperemia of small arteries and their surrounding branches on the skin caused by excessive secretion and insufficient inactivation of estrogen in the body. If we observe a typical large spider nevus, we can see its pulsation. If we use the cap part of a thin stick or a big nail to press its central part, the nevus will disappear completely, and it will appear again quickly after picking up. All these indicate that the basic structure of spider nevus is arteriole.

How is spider mole treated

First, spider nevus is easy to be confused with vascular nevus and should be distinguished. Vascular nevus is characterized by: the shape of a small dot like red nevus, no radial network around the congestion of small blood vessels, pressure does not fade, does not disappear, the number of its size and number is often proportional to age, that is, the older the age, the more such vascular nevus.

Second, the location of vascular nevus is different from that of spider nevus, which is mainly distributed in abdomen, back and chest, while spider nevus is mainly distributed in the area of distal superior vena cava vessels, such as neck, face, chest above nipple level and inside of anterior buttock.

Third: spider nevus, after all, is a common sign of liver cirrhosis on the skin. In male patients with spider nevus on the body surface, 85% of the liver tissues showed abnormal changes, and 1 / 3 of them were liver cirrhosis. After close observation and combined with clinical and laboratory studies, it was found that the appearance, development and regression of spider nevus are closely related to the progress of liver cirrhosis.

matters needing attention

If a person's skin appears spider nevus, especially a large number, one after another; or spider nevus appears after a long time, typical shape, to be alert to the possibility of cirrhosis, active medical treatment.
