Change in the density, structure, color of skincovers occurs under the influence of internal / external stimuli.

  1. Allergy. Allergens can be cosmetic and cleaning products, pet hair, food. The allergic reaction is manifested by small specks, which gradually turn into flaky foci and itchy blisters. Complex treatment: the exclusion of contacts with the allergen plus the use of antihistamines.

  2. Atopic dermatitis. It manifests itself as condensed scaly patches on the legs / hands. A distinctive feature of the disease is the activation of the rash in winter, fading in the summer. Atopicdermatitis is a chronic pathology, the correction of the skin condition is carried out with the help of hormonal ointments.

  3. Mycosis. Fungal infections provoke the appearance of a rash on the toes and toes. As the disease progresses, the pathological process quickly spreads to neighboring healthy tissues. Treatment of mycosis includes local (treatment of affected segments with antimycotic drugs) and general (antimycotics) therapy.

  4. Viral infection. Small red dots and spots on the hips, legs, feet, appearing simultaneously with fever, feverish condition, general malaise, may indicate an infectious disease - rubella, measles, chicken pox. Eruptions quickly enough transformed into papular tumors, accompanied by hyperemia, swelling, itching. Therapy involves the use of antiseptic, drying agents, immunomodulators.

  5. External influence. A rash on the skin of the legs can result from chemical / thermal burns, frostbite / weathering, bruises, insect bites. Also worth noting the sun and its rays - from which the white skin can become covered with spots.

  6. Systemic diseases:

    • diabetes. Dermopathy with diabetes appears symmetrically on both legs. The spots have a red-brown color and a small diameter (up to 1 centimeter). In 10-15% of cases, the patient develops the ringed granuloma Darya - the rashes focus on the trunk and legs, at the first stage they look like pinkish swollen spots, on the second they start to merge, forming original patterns;

    • phlebeurysm. The first sign of varicose veins is red spots and heaviness in the legs. The triggered disease leads to thrombophlebitis and trophic ulcers, which are difficult to treat traditionally;

    • vasculitis. Disease multifactorial nature, characterized by inflammation of the subcutaneous tissue and blood vessels of the dermis. Clinic of cutaneous vasculitis: the formation of red spots of papular-hemorrhagic nature on the legs and buttocks, joint pains - articular syndrome (pain in the ankle / knee joints), fever, blood in the stool, tenderness of the abdomen, vomiting.

  7. Vegetative dysfunction. It can be latent (leaky) pristupoobraznoy or permanent. It is manifested by panic attacks, digestive tract disorders, dizziness, irregular blood pressure, the appearance of red spots on the lower / upper limbs. Treatment of vegetative-vascular dystonia requires the appointment of medications of various pharmacological groups - neuroleptics, antidepressants, nootropics, tranquilizers.

  8. Hives. Occurs when in direct contact with nettle. Typical symptomatology: red spots on the limbs, reminiscent of blisters, bruises, intense itching. After finding out the reason that provoked such a reaction, contact with the allergen should be eliminated, otherwise the further development of the process, resulting from itching to Quinck's swelling, suffocation, and death, is not ruled out.

  9. Teleangiectasia (vascular asterisks). A syndrome characterized by vasodilation, the formation of bluish-red spots on the skin of the legs, less often - the trunk, face. The most effective ways to treat telangiectasia of the lower extremities are laser photocoagulation and sclerotherapy.

  10. Thrombocytopenic purpura (Verlhof disease). It differs by two mutually exclusive signs: on the one hand, blood clots are formed in small vessels, which leads to a stop of blood flow, on the other - blood clots are not formed and bleeding begins. As a result, the surface of the limbs and trunk is covered with purple spots. The prognosis is usually favorable, the mortality rate is 4% after the initial hemorrhagic attack, 8% - after repeated attacks.

  11. Alcohol can also cause spots.
