Small red moles on the body are considered to be vascular nevi or spider nevi, and may also be bleeding spots. Vascular nevus is mainly a congenital dysplasia that leads to dilated and proliferated blood vessels. Spider nevus is mainly caused by the expansion of arteries and their branches in the superficial layer of the skin, and bleeding spots may be related to abnormal coagulation function of the body or other diseases.1. Vascular nevus: It can appear as papules and small nodules above the surface of the skin, which can appear in any part of the body and will not fade after pressing. Vascular nevus will not develop to a certain extent and will not deteriorate, so it usually does not need treatment. If it affects life or for aesthetic reasons, it can be treated with glucocorticoids, prednisone and other drugs, and it can also be treated by laser or freezing, or directly removed by surgery. 2. Spider nevus: It is usually caused by changes in estrogen levels in women or liver diseases such as cirrhosis and chronic hepatitis. They mostly occur on the face, neck and hands, and will fade when the center of the spider nevus is pressed. Usually, spider nevi caused by changes in hormone levels during pregnancy and puberty are physiological and can be treated without treatment. In the case of patients with liver disease, active treatment of the primary disease is required. For those who feel that it affects the beauty, it can be removed by applying laser, electrocautery, freezing, etc.; 3. Bleeding dots: In this case, the small red dots appearing on the skin usually do not bulge on the skin, but can appear widely on the skin, mucous membranes, etc., and will not fade with hand pressure. The appearance of bleeding dots may be related to the skin clotting factors, platelet count abnormalities, bleeding disorders, etc. You can follow medical advice to perform blood-related tests such as coagulation function to clarify the specific cause of the disease, and then treat the cause.
