Erythema nodosum – causes, symptoms, treatment

Erythema nodosum, also known as erythema nodosum, is a skin disease that can cause many problems for patients. In this article, we will take a closer look at this ailment, its causes, clinical symptoms, methods of diagnosis, differentiation from other diseases, treatment and prevention options. Let’s find out more about this interesting disease.

What are the causes of erythema nodosum?

Erythema nodosum is a disease whose etiology is not fully understood. However, there are several factors that may contribute to its development. One of the most important is the body’s immune response to various factors, such as bacterial infections (e.g. tuberculosis), viral infections (e.g. Epstein-Barr viruses, HIV), fungal infections, or drugs. Moreover, erythema nodosum is often associated with other diseases, such as sarcoidosis, systemic lupus erythematosus, or celiac disease.

What are the main clinical symptoms?

The symptoms of erythema nodosum are characteristic and easily recognizable. The most important symptom is painful, erythematous nodules or lumps that appear mainly on the lower limbs, especially the shins. These nodules may be solitary or appear in groups. They may be accompanied by joint pain, fever, fatigue and general malaise.

So how to recognize the disease?

The diagnosis of erythema nodosum is based mainly on the observation of characteristic clinical symptoms. Your doctor may also order blood tests and other tests to rule out other possible causes of skin lumps. It is also important to identify the factors causing the disease, such as infections or medications.

How should erythema nodosum be differentiated?

Erythema nodosum may be confused with other skin diseases, such as lichen planus or vasculitis. Therefore, it is important to consult a dermatologist who will carefully assess the symptoms and order appropriate tests to make the correct diagnosis.

What is the treatment for erythema nodosum?

Treatment of erythema nodosum consists mainly in combating the cause of the disease. If the disease is caused by an infection, the doctor prescribes appropriate antibiotics. In case of reactions to medications, they must be discontinued. Additionally, anti-inflammatory medications such as non-steroidal anti-inflammatory drugs (NSAIDs) are used to help reduce pain and swelling. In more severe cases, steroid therapy may be necessary.

Can erythema be prevented?

Unfortunately, there is no effective prevention of erythema nodosum because its causes are not fully understood. However, avoiding triggers such as infections and medications can help reduce the risk of developing this disease.
