Skin tags are not directly related to AIDS. Cutaneous urticaria is a common type of chronic urticaria in which the patient develops a certain physiological reaction to a weak external mechanical stimulus, resulting in the production of a certain amount of wind mass on the skin. The disease can occur at any age and may produce localized lesions with itching after scratching or loosening of belts and shoes and socks. The cause of this disease is not well understood, but in some cases it may be related to the presence of abnormalities in the mast cells of the patient’s body, without an increase in the number of mast cells. In some cases, it may be induced by penicillin, but it is not directly related to AIDS. AIDS is mainly an infectious disease caused by infection with the human immunodeficiency virus, so there is no direct relationship between the two.
