Blood mole, i.e. red mole, is caused by continuous expansion of local capillaries on the body surface or mucous membrane, resulting in skin lesions, which may be related to liver and gallbladder diseases, or may be cherry-shaped hemangioma, as follows: 1. caused by liver and gallbladder diseases: blood mole is generally red or brown, does not fade when pressed, varies in size, is not painful or itchy, mostly higher than the skin surface, mostly seen in patients with fatty liver, chronic hepatitis, gallbladder polyps, mainly It is because when liver and gallbladder lesions occur, the inactivation of estrogen by the liver will be weakened, so that estrogen will accumulate in the body and red mole symptoms will appear on the body; 2. Cherry-shaped hemangioma: that is, vermilion mole, which occurs in the elderly and may be related to skin aging, generally does not require special treatment and can be done by moisturizing and sunscreening the skin in general. If blood nevus appears, it is recommended to improve the examination and clarify the cause. If it is caused by liver and gallbladder disease, priority should be given to treating the primary disease, and the bloody nevus will also be eliminated in a certain period of time after healing. If it is related to cherry hemangioma, it is usually not treated. If it is for aesthetic purposes, you can also choose a regular hospital to perform ion cautery, liquid nitrogen freezing treatment, or to remove it surgically.
