Red spots on swollen legs

Human skin is not just a fabric,covering the whole body from the outside. It is a huge organ that protects us from outside effects: microorganisms, pressure, temperatures, chemicals. In addition, the skin is closely related to our internal environment, and when there is some kind of malfunction, it gives them a general or local change in structure, elasticity and color. Thus, red spots on the legs, like a rash of a different nature in this localization, is a signal that problems are occurring with the body. They, in order to avoid dangerous consequences for health, must be identified and eliminated. Consider how the rash appears in the most common diseases.

Under the spot, people mean a local changecolor and (sometimes) and the structure of the skin in a certain localization. Doctors also use the word "spot" to refer to a small area of ​​altered color (red, brown, black or whiter than the surrounding skin), which does not rise above the rest of the cover. Elements that protrude above the surrounding skin, flaking, with a density different from other tissues, having a cavity filled with light water or pus, have completely different names. This helps doctors to narrow the "circle of suspected" diseases.

In order not to confuse the reader, the "stain" in this publication will be called all elements of the rash. As a basis, let's take a classification, according to which the spots are vascular or pigmented.

This formation of red, purple,brown, bluish or yellow. Their color depends on the state of the blood in the localization: in which vessel (blood or lymphatic) it is located, whether it has left it in the tissue or continues to be included in the bloodstream.

  • those that are associated with the temporary expansion of the vessel (for example, with allergy, infectious disease, burn - chemical, thermal or ultraviolet);
  • associated with the constant expansion of the vessel: "vascular asterisks", hemangiomas;
  • hemorrhagic spots - caused by the release of blood from the capillary

These spots developed as a result of increasedor a reduced content of melanin (the brown pigment that is contained in the skin cells and makes our tan possible). If there is a lot of pigment, moles, chloasma, freckles, lentigo appear. When it is small, on the skin appear whitish areas: vitiligo, leukoderma.

There is another type of stain, which arises from the artificial injection of dye inside the skin (tattooing, tattooing), but this is not a disturbing problem, and we will not consider it.

Red spots on the legs in adults

Rash red in children

The spots on the legs of a child often appear due to:

  • Allergies. on a new powder for washing clothes, diapers or diaper remedies, new means for bathing, after an insect bite, in response to cold or a sharp alternation of heat and cold. In this case, the spots rise above the skin, almost always - itch, which causes sleep, food. Helps to comply with the hypoallergenic diet, the intake of sorbents ("Atoxil", "Smecta", "Activated Carbon") and antihistamines (Fenistil, Suprastin, Erius).
  • Enterovirus infection. In this case, the rash is most often located not only on the legs, but also on the hands, mainly on the fingers. It looks like bubbles surrounded by a red border, almost always - itchy.

  • Corey. Here the red spots on the legs appear in the last place: first the rash appears on the face, and then descends, merging with each other. In addition, the temperature rises, the snot begins to flow from the nose, conjunctivitis and edema of the eyelids are noted.
  • Scarlet fever. It is a disease that is caused by the same bacteria as angina. Red spots, when pressed on, they show better, appear on the 1-3 days of the disease, are located on the cheeks, on the sides of the body, and not on the legs, but in the groin.
  • Meningococcal infection. This is a life-threatening condition that can begin with the fact that after 1-2 days a cold (or even without it) on the legs and buttocks there are spots, the temperature rises, the spots spread to other parts of the body. In the beginning, they can be red without pustules or bubbles. Then they darken, get a star shape, merge. Dark spots on the legs, which do not disappear when the skin is pressed with a transparent glass, can appear immediately, without the stage of the red fluid elements. The earlier "Ambulance" is called, the more chances a child has to survive.
  • Pink depriving. Its manifestations are described above.
  • Shorthaired lichen. There are several such spots, it is brownish-red, cover different parts of the body, do not merge, the skin over them peels off. The shape of the spots is different, they tend to merge, do not itch and do not hurt. When the rash disappears, on these places there are whitish areas.

There may be spots in children due to ringworm and other mycoses, but these reasons are more rare than the above.

As mentioned above, this rash associated withbrown pigment melanin, contained in our skin is normal, but located in it evenly. Under the word "pigment" there are spots in view of the excess of melanin. It:

  • Moles - brown or black spots, located anywhere in the body, from which in some cases the hair grows;
  • Melasma. large dark spots, which are more common in pregnant women on the white line of the abdomen and on the face, but can accompany some internal diseases and be on their feet;
  • Freckles. multiple small brown spots on the legs
    various shades of brown, usually located in accessible light places of persons with fair skin;
  • Lentigo - dark brown and black spots on thelegs, arising either before 10 years of life, or in the elderly in open areas of the body. If such a raging element itches or flakes, this indicates malignancy of the process;
  • Secondary hyperpigmentation. They occur at the site of ongoing epilation and depilation, after the removal of different formations of the laser or electrocoagulation - if after the procedure the legs in the first month felt the ultraviolet rays without sunscreen. They can occur with a deficiency of certain vitamins, such as ascorbic acid, retinol, nicotinic acid.

Pigmented also include depigmented, that is, light areas. It:

  • Vitiligo. white spots of different shapes and sizes, appearing as a response to frequent stresses and chronic diseases of the cavity organs (especially - the liver). They have such an effect: white spots appear to be circled in color, darker than the surrounding skin, which gradually merges with the usual skin.
  • Leukoderma. this is the appearance of light areas of the skin as a result of a systemic disease. If white spots without clear boundaries appeared on the trunk and on the legs, this may indicate syphilis.

On the pigmented spots - because they have a brown color - similar hemorrhage arising from diseases of the vessels, with the pathology of the coagulating system:

  1. Thrombocytopenic purpura. Here the rash is not only on the legs, it appears spontaneously, after sleep, asymmetrical, visible as dark spots, and purple, and yellowish-green (like the phases of the bruise).
  2. Hemorrhagic vasculitis. Here, brown spots appear immediately on the legs, symmetrically on both. The form of rashes is different, they tend to merge. When the disease affects the joints too, the stomach may ache, the work of the kidneys and brain may be disrupted. This pathology requires urgent medical correction.
