Dermatology - diseases of the skin

Erythema Nodosum

Erythema nodosum is a disease characterized by inflammation of the blood vessels of the skin and subcutaneous fat. Most common in women (three times more often than men), ranging in age from 15 to 30 years. The causes of this disease are very diverse and not combined between themselves.

Causes of Erythema Nodosum

This causes various infection: streptococcal infection (tonsillitis,scarlet fever), tuberculosis, yersiniosis, and venereal limfogranulema, leprosy, histoplasmosis, coccidiodes. In short, all what we call “chronic foci of infection”.

Non-infectious: sarcoidosis (a fairly common cause of erythema), non-specific ulcerative colitis.

You also need to mention the allergic nature of the erythema, which most often occurs in the reception sulfa drugs (sulfalen, sulfadimetoksin), contraceptives.


Symptoms and causes of erythema nodosumThere are acute form of the disease and chronic. The acute form is characterized by deterioration of General condition, fever, the appearance on the shins, knees, and rarely the face, neck catch, painful on palpation, with a red color, changing to purple, then brown and yellowish. In half of the cases observed inflammation of the joints. More severe erythema nodosum occurs in children. The process allowed their own over 6-7 weeks.

In the chronic course of this condition is not held for a long time, nodes tend to merge or emerge in new places after the old permit, that is, migrate.


For causes and treatment it is necessary to consult a dermatologist, a rheumatologist, a physician or your doctor if the cause is known (TB – visitor, sarcoidosis, the pulmonologist, etc.).

Moreover, so that You set a correct diagnosis and not confuse erythema, for example, tuberculosis of the skin, so it is necessary to understand the reasons which can be very serious. To this disease priminitelno approval old clinicians: “the Skin is the barometer of the internal environment of the organism”.

The diagnosis of erythema nodosum exhibited by visual inspection. At first contact it is advisable to take a smear from the oropharynx to the Streptococcus and to make a lung radiograph to exclude sarcoidosis and tuberculosis and pass a stool for Yersinia.

Treatment of Erythema Nodosum

Treatment of erythema nodosumTreatment is prescribed depending on the causes. I would advise the patient to go into a hospital and get tested “head to toe”. In most cases, this condition is unlikely to allow You to fully perform the work, even not related to physical labor.So the sick list is still needed.

For the treatment of erythema nodosum, the following group of drugs: nonsteroidal anti-inflammatory drugs (nimesil, indomethacin), hormones (prednisone), which do not follow to take in infectious processes, and in allergic will come in very handy, potassium iodide orally (if no contraindications), antibiotics in infectious process. Local treatment (heparin ointment).

Folk remedies are used together with primary treatment. Some grasses, herbs added to the diet: green beans, beans, Basil, dill, caraway. For edema diuretic used fees.

But we must remember that they will not disclose and will not cure the root cause, only are “strings”, for a successful resolution process and alleviate the condition.

Until the disappearance of the acute stage of the disease must observe polupostelny mode. The diet is lacto – vegetarian. After suffering erythema should exclude physical activity for at least 1 month.

Summarizing, we can say that the treatment of erythema – the art, subject only to doctors specialists, but not all.


The risk of acute erythema consists in its transition to the chronic. Therefore, the most courageous gentlemen would like to protect you from the tranquility that everything will be solved by itself after 6 to 7 weeks, about which I spoke above and of which so much is written in educational literature. Definitely need to be treated.

And, of course, nobody cancelled and the mass of complications that result from all the serious diseases which signals the skin the appearance of erythema nodosum.
