What is purpura simplex?

In life, purpura simplex usually occurs in women, and red spots often appear on the lower limbs and buttocks. Since purpura simplex is self-healing, most people do not take it seriously, and many people have never even heard of this disease. So what is purpura simplex? Simple purpura refers to a hemorrhagic disease in which purpura appears spontaneously and repeatedly on the skin, especially on the lower limbs, without any other symptoms and disappears on its own without treatment.

Purpura simplex is also known as livedo syndrome. This is a type of purpura caused by vascular factors, which is more common in women. Its clinical characteristics are spontaneous appearance of petechiae or ecchymoses on the lower limbs and buttocks, rarely on the upper limbs, and not on the trunk. Purpura may worsen during menstruation, but it may disappear on its own without treatment. The arm restraint test was positive, and other hemostatic functions were normal. No bleeding occurs in internal organs or other parts.

The cause and pathogenesis of this disease are not yet fully understood. It may be caused by an abnormality in the capillary walls. The arm restraint test was positive, other hemostatic functions were normal, and no bleeding occurred in the internal organs or other parts. This disease often occurs in multiple cases within a family. It is mainly seen in women and rarely in men. It has a gender predilection and mainly occurs before menstruation, which may be related to endocrine. In addition, some people have suggested that abnormal platelet function in some patients is also one of the mechanisms leading to this disease.

Although the above are only possible causes, if similar erythema appears on your body and you want it to disappear quickly, you can go to the hospital to consult a relevant professional doctor and take some medicine. I believe you will recover soon.

Symptoms of simple purpura

Simple purpura is more common in women. Its clinical features are tiny petechiae and ecchymoses of varying sizes on the skin, which are common on the lower limbs and buttocks, and rarely occur on the trunk. There are no predisposing factors. The disease recurs frequently, and is more likely to occur during menstruation. In a small number of patients, the arm restraint test may be positive. This disease also occurs frequently during the menstrual period in children and adolescent girls. Most of the time, bleeding spots or bruises appear repeatedly on the skin of the lower limbs and buttocks. These spots do not bulge on the skin surface and do not fade when pressed. After a few days or weeks, the purpura subsides and leaves blue or yellowish-brown pigmentation spots, which then gradually disappear. Skin purpura may reappear and occur repeatedly. Simple purpura is occasionally seen on both upper limbs but not on the trunk. Some patients experience local skin pain when purpura appears, which is generally not severe. Some patients may also be caused by autosomal dominant inheritance, which is more common in women with a positive family history, called familial simple purpura.

In addition, the bruises or petechiae of simple purpura vary in size and are unevenly distributed. They do not protrude above the surface, do not fade or hurt when pressed, and there may be slight local pain before the bruises appear. However, if this disease is not treated, the bruises may disappear on their own, leaving behind bluish-yellow pigmented patches that gradually disappear. Sometimes purpura will recur frequently and worsen during menstruation. Patients generally have no bleeding in the internal organs or other parts of the body, mucosal bleeding is rare, sometimes there is a small amount of bleeding from the gums, increased menstrual flow, and prolonged menstruation. The amount of bleeding may be slightly more during tooth extraction, surgery, trauma, and childbirth, but it will not cause severe bleeding.

In addition to the clinical symptoms, simple purpura may also cause certain complications, the most common of which are moderate lymphocytic infiltration and hemosiderin deposition in the upper dermis, and dilation of small blood vessels.
