For a normal shade and even skin color, the pigment cells respond. Violation of their formation and functioning leads to the appearance of red spots on the legs and other parts of the body. In addition, this symptom can be provoked by vascular pathologies associated with internal and external damage to the walls of small arteries and veins.
The causes of the appearance of red spots on the legs
As indicated, the problem under consideration is provoked by two main factors - pigment and vascular disorders. The second type, in turn, is divided into the following types of spots:
- Oedemas. Occur due to local delay in excess fluid, which leads to a worsening of blood circulation.
- Hemorrhagic. Observed due to hemorrhages in the upper layers of the dermis.
- Inflammatory. They are formed due to a sharp pathological expansion of the lumen of the vessels, thinning of the walls.
More details on each type of symptoms are discussed below.
On the feet there were red spots without other signs
There are several reasons for explaining this clinical phenomenon:
- irritation after depilation and depilation;
- an allergic reaction to cosmetic products or other histamines;
- mechanical damage to the skin after wearing synthetic, tight clothes.
It is worth noting that the allergy in the form of red spots on the feet often arises from the intake of certain medicinal preparations, products, is the immune response to contact with animal hair, household dust.
In such situations, the problem is solved quite simply, by eliminating irritants from everyday life, changing hygienic cosmetics, clothing, ensuring the skin is properly maintained. But more often the considered pathology has more serious reasons.
Red spot on her leg itches
Itching, as well as peeling, compaction or ulceration of tumors may indicate the presence of the following diseases:
- psoriasis ;
- hemangioma;
- eczema;
- vasculitis;
- dermatitis;
- syphilis;
- hemosiderosis;
- roseola;
- mycosis (often accompanied by itchy red spots on the soles of the feet and fingers);
- Bowen's disease;
- pink lichen;
- streptoderma.
The most rare disease in this list is hemosiderosis. It is characterized by the appearance of red-brown formations on the skin of the legs, which eventually spread to other parts of the body.
Hemangioma - a benign tumor, looks like a bright red or scarlet spot, slightly protruding above the surface of the epidermis.
The most difficult to cope with psoriasis, because this pathology has an autoimmune origin and is considered incurable today.
Eczema, dermatitis, vasculitis, roseola, lichen, syphilis and streptoderma belong to inflammatory lesions due to the entry into the body of a viral or bacterial infection.
Mycosis is caused by the reproduction of yeast-like fungi on the surface of the skin, rapidly spreading, causes unbearable itching.
Bowen's disease outwardly resembles psoriasis, but without timely therapy can develop into cancer (squamous).
Red spots on the lower leg
This phenomenon is most typical for diabetes mellitus. In this case, the spots have clearly defined edges, very different in color from normal skin. It is important to begin their treatment immediately, since such formations quickly develop into trophic ulcers.
Also on the shins appear patches of red-violet, sometimes with a blue, due to circulatory disorders - varicose veins, thrombocytopenic purpura , thrombophlebitis. As a rule, they are accompanied by weakness, pain in the limbs, aching joints.
