Dark spots

As mentioned above, this is a brown pigment rash.
melanin contained in our skin is normal, but located in
her evenly. Under the word “pigment” there are spots in mind
excess of melanin. It:

  • Moles – brown or black spots located in any
    place of the body, of which in some cases hair grows;
  • Melasms: large dark spots that are more common
    in pregnant women on the white line of the abdomen and face, but may accompany
    some internal diseases and located on the legs;
  • Freckles: multiple small brown spots on the legs
    different shades of brown, usually located on
    accessible to light areas of fair-skinned persons;
  • Lentigo – dark brown and black spots on the legs, arising
    or up to 10 years of life, or in old people in open areas of the body. If a

    epilation and depilation, after removal of various formations of the laser
    or electrocoagulation – if after the procedure of the leg in the first month
    felt the ultraviolet rays without sunscreen.

    ascorbic acid, retinol, nicotinic acid.

The pigmented also include depigmented, that is, light
plots. It:

  • Vitiligo: white spots of different shapes and sizes, arising as
    response to frequent stresses and chronic diseases of the abdominal organs
    (especially – the liver). They have this effect: white spots
    as if circled in color, darker than the surrounding skin,
    which gradually merges with the normal skin.

    systemic disease. If a белые пятна без четких границ
    appeared on the torso and on the legs, this may indicate
    syphilis.

Hemorrhagic spots

On age spots – due to the fact that they are brown
– similar hemorrhages occurring in vascular diseases, with
pathology of the coagulation system:

  1. Thrombocytopenic purpura. Here the rash does not range.
    only on the legs, arises spontaneously, after sleep, asymmetrical,
    visible as dark spots and purple, and yellowish-green (as
    bruise phases).
  2. Hemorrhagic vasculitis. Here brown spots arise
    right on his feet, symmetrical on both. The shape of the rash is different, they
    tend to merge. With the disease also affects the joints, can
    hurt the stomach, disrupt the work of the kidneys and brain. This
    pathology requires urgent medical correction. More about

localization in children under 14 years old (and especially if it is dark or
star) is required for an emergency examination by a pediatrician
Polyclinics (in the daytime) or in-patient departments – at night and

analyzes like:

  • general blood and urine tests;
  • blood glucose;
  • bacterial culture from affected skin;
  • blood chemistry;
  • Ultrasound vessels of the legs.

Based on inspection, laboratory and instrumental
diagnosis doctor will establish a diagnosis and prescribe therapy. Self-medication
you should not do it: even if the rash under your “treatment” has passed,
it cannot be said that the disease has not passed to the next stage,
when the internal organs are affected.
