Erythema: Symptoms and Treatment

Erythema — abnormal redness of the skin, which develops if the blood in excess amounts to the capillaries. In some cases, this condition can be an absolutely normal and conditioned phenomenon, the symptoms of which disappear for a short time.

But prolonged redness of the skin can indicate the presence of a pathological process in the human body. The cause of its progression is most often inflammation, infectious agents (bacteria, viruses, etc.).


Progression of erythema may be triggered by several causes. Separately among them is to identify infectious ailments, skin diseases (dermatitis). Often, erythema can occur as a result of impaired blood circulation in the skin, due to allergic reactions, and also after carrying out physiotherapy procedures, during which an electric current is used.

Redness of the skin also often results from chemical or sunburn (solar erythema), intense skin friction, and other actions that could trigger the expansion of the capillaries.


In medicine, there is a fairly large number of clinical forms of erythema skin, but separately it is worth noting these:

  • knotty (nodular) erythema of the skin;
  • annular erythema or centripetal erythema Darya
  • Migrating;
  • solar erythema;
  • infectious (viral)
  • toxic or erythema in newborns
  • erythema multiforme or erythema polymorph
  • exudative erythema;
  • palmar erythema or erythema of the palms.


Symptoms of pathology are quite diverse. It is worth noting that each form of pathology has its own symptoms.

Knot form

In this case, red spots are localized on the surface of the skin. When feeling, you can find that their structure is dense. They give the patient discomfort. Pathological formations can disappear spontaneously, but can last for several days. With this skin erythema, the inflammatory process is localized in the subcutaneous adipose tissue, as well as in the thickness of the skin itself. The sizes of knots various — from 1 sm up to 10 see Usually knots are localized on shank and on the internal party or side of a femur.

Sometimes the progression of the disease contributes to viral pathology. In this case, the main clinic is supplemented with the following symptoms: general health deteriorates, the temperature rises, joint pains, inflammation of the mucous eye is possible.

Ring-shaped shape

Pathology begins to progress because of infectious ailments, poisoning of the body, allergic reaction. In this case, the skin of a person has spots of rounded shape, which tend to merge. They can protrude somewhat over the skin. The periphery of the ring is colored red. The central part of education is normal color. Size — from 2 to 8 cm in diameter.

The migrating form

This is a chronic illness. Usually it develops after a bite of a forest mite. Outwardly manifested first in the form of a red speck, which begins to grow rapidly as the pathology progresses. Peeling is not observed. Symptoms of pathology can disappear on their own in a couple of months. But it is also possible and the development of complications (CNS damage).

Solar form

Solar erythema is a pathology that develops as a result of prolonged exposure to the skin of the ultraviolet. It is worth noting that for the life of the patient there is no danger of illness. Symptoms of solar erythema:

  1. skin blushes after prolonged exposure to direct sunlight
  2. the affected areas begin to itch;
  3. Bubbles are formed at the site of erythema localization, which can spontaneously open with the release of exudate
  4. After a few days, the affected areas begin to peel off.

Erythema infectious

The causes of its progression are pathogenic microorganisms.


  • temperature increase;
  • chills;
  • signs of body intoxication
  • pathological spots are formed on the body, which tend to merge (large foci may be formed).

Toxic form

This form is also called erythema of newborns, as it manifests itself in babies in the first few days of their life. On the skin of the baby there are rashes that spontaneously disappear, so no specific treatment is required. A slight increase in temperature is possible with erythema of newborns.

Erythema in children in the first days of life is a peculiar symptom of the adaptation of their organism to the external world. On the body are formed red spots, which have a more dense structure than the rest of the tissue. Sometimes small bubbles may appear on them, filled with serous exudate inside. Usually the formations are localized on the head, on the folds of the legs and arms, on the buttocks.

Erythema multiforme

Polymorphic exudative erythema can affect both mucous membranes and skin at the same time. It is more susceptible to young men of the male sex. This form of pathology is much worse than the rest — the symptoms are very pronounced:

  1. increase in body temperature;
  2. pain in the muscles and joints
  3. First, pathological spots are formed which later degenerate into blisters filled with serous or hemorrhagic fluid
  4. rashes painful and itchy
  5. keratitis or conjunctivitis may develop.

It is worth noting that if the pathology proceeds in severe form, then even a lethal outcome is possible.

Exudative form

Exudative erythema is an inflammatory disease that affects the mucous membrane and the skin. As a result of its development, red spots, blisters and other elements of the rash are formed on the affected skin areas. Exudative erythema occurs in an acute form, but there is a possibility of its transition into a chronic.

Excitatory erythema causative agents:

  • Streptococcus
  • Staphylococcus;
  • herpes virus and other microorganisms

Fixed erythema

Fixed erythema is a unique reaction of the body to the introduction of a certain drug into the body. These substances include antibacterial drugs, NSAIDs, hypnotics, oral contraceptives, tartrazine and others.

Palmar shape

Palmar erythema is a pathology in which symmetrical reddening of the palms is observed. Most often this is observed in chronic liver diseases, pregnancy, rheumatoid arthritis, leukemia and others. It should be noted that palmar erythema can occur on the body even in healthy people.


Treatment of erythema should be only complex. The first stage is to identify and eliminate the true cause, which triggered the progression of pathology. For example, cure infectious diseases, abandon procedures that can irritate the skin and so on.

The second stage is drug treatment. Assign to take antibiotics, corticosteroids, angioprotectors and so on. Sometimes doctors prescribe drugs containing substances that strengthen the walls of blood vessels.

Treatment recommendations:

  1. bed rest;
  2. Exercise;
  3. dieting

  4. refusal of allergens — alcohol, chocolate, citrus, coffee, etc.
