What does "spider mole" mean?

Spider hemangioma is formed by a central arteriole and many tiny blood vessels radiating outward. It is named after a spider. Some people are scared to death as soon as they find out that they have spider moles, which will also appear in normal life. Pathological spider nevus is common in acute and chronic hepatitis or cirrhosis, but also in pregnant women and healthy people.

Spider nevus is as small as a needle cap, and the diameter of large spider nevus can reach more than 1cm, with a slightly raised center. If you press the central erythema with the needle cap, the surrounding capillaries will subside, and will recover after the pressure is released, which usually appears in the areas where the superior vena cava is distributed, such as hands, face and neck, chest and shoulders.

The incidence of spider nevus in patients with acute hepatitis is about 65438 0%, while that in patients with chronic hepatitis can reach about 54%. The appearance of spider nevus is often parallel to the state of liver function. When liver function deteriorates, spider nevus can increase sharply. After the liver function improves, spider nevus can change from bright red to brownish black, and then disappear.

Don't panic when we find spider moles on our bodies. It is necessary to carefully analyze the causes of spider nevus and whether there are symptoms of liver disease such as hepatitis and cirrhosis. If the symptoms of liver disease are accompanied by spider nevus, you should go to a specialized hospital for hepatitis B examination or liver function examination to see if there is liver disease. If so, we can make early diagnosis and treatment.

Generally speaking, the appearance of spider nevus is caused by the increase of estrogen in human body. Estrogen has the function of dilating blood vessels and is secreted by women's ovaries and men's adrenal glands. Estrogen can't exist too much in the human body and is inactivated by the liver. Because the liver of patients with hepatitis B is damaged, the ability of the liver is decreased, and estrogen can not be effectively inactivated, which leads to the accumulation of estrogen and the appearance of spider nevus. Spider nevus may appear on people's face, neck, chest and back. The most typical form is a little red dot on the body surface with radial blood vessels around the red dot. Press it to fade, release it to recover.

The appearance of spider nevus is a very serious matter for patients with hepatitis B. For patients with hepatitis B, the appearance of spider nevus may be a manifestation of the deterioration of the disease and a sign of the development of cirrhosis. Therefore, if patients with hepatitis B find spider nevus, they should go to a professional liver hospital for examination and treatment, so as to avoid the deterioration of their condition and bring difficulties to treatment.
