Causas del eritema nodoso
As it is a lesion produced as a result of an immune response, erythema nodosum is usually caused by immunological processes produced by different stimuli, such as:
- Infectious processes: Those most closely related to erythema nodosum are infections of the upper airways caused by streptococci. However, it can be caused by the conditions of many different microorganisms.
- Medications: It has been possible to positively link the appearance of erythema nodosum with the consumption of certain medications, among which the most common are penicillins, oral contraceptives, sulfa drugs, and others.
- Diseases: The most linked are lymphoma , leukemia, sarcoidosis, and systemic lupus erythematosus.

Erythema nodosum symptoms
Erythema nodosum is characterized by the very characteristic appearance of lesions that appear mainly on the anterior aspect of the calves of both legs. However, they can also appear on the forearms, thighs, and trunk. They are painful, circular, hot lesions that measure between 1 and 5 centimeters, that appear suddenly and in the first instance may appear elevated, but with the days, they flatten. Their color on the first days is red, but they change to purple and then yellow over time. They appear for eight to ten days, after which the appearance stops, and the lesions that have occurred will recover during a period that can vary from one week to 2 months after the arrival. In the photos, you can see how the lesions are caused by erythema nodosum.
Other symptoms that accompany erythema nodosum are usually:
- General discomfort
- Joint pain
Diagnóstico del eritema nodoso
Because the symptoms and form of appearance of erythema nodosum are very particular, the diagnosis of this condition can only be made with a history and clinical examination. Some experts, however, recommend performing a biopsy of any of the lesions to differentiate it from other processes that may have a similar presentation, such as:
- Vasculitis nodular
- Subcutaneous lymphoma
- Cutaneous panarteritis nodosa
Treatment of erythema nodosum
As it is a benign lesion with minimal possibility of complication, erythema nodosum usually has an excellent prognosis. Its resolution is generally practically spontaneous, requiring only symptomatic treatment for discomfort, pain, and other systemic symptoms, for which it can. The use of commonly used analgesics, such as naproxen or ibuprofen, will suffice. However, rest is even more favorable to stimulate a quick recovery, taking up to 2 months.
Because a good part of the erythema nodosum is caused by other diseases, the treatment often focuses more on the resolution of these diseases, for example, the improvement of an infectious process in the respiratory tract.
