Common Causes of Erythema Nodosum

Erythema nodosum is a condition characterized by painful, tender nodules that appear under the skin. While the exact cause is not always known, there are several common factors that can contribute to the development of erythema nodosum.

Infections such as streptococcal throat infections, tuberculosis, and fungal infections can trigger erythema nodosum. These infections cause an immune response in the body, leading to the characteristic skin lesions.

Autoimmune diseases like rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease can also cause erythema nodosum. In these conditions, the immune system mistakenly targets the body’s own tissues, resulting in inflammation and the formation of nodules.

Medications such as antibiotics, oral contraceptives, and nonsteroidal anti-inflammatory drugs (NSAIDs) have also been associated with erythema nodosum. These medications can trigger an immune reaction that leads to the development of the skin lesions.

Other underlying conditions, including sarcoidosis, Behçet’s disease, and certain cancers, can contribute to the development of erythema nodosum. These conditions cause inflammation in various parts of the body, resulting in the characteristic nodules.

Understanding the common causes of erythema nodosum is essential for healthcare professionals in diagnosing and managing the condition effectively. By identifying the underlying cause, appropriate treatment strategies can be implemented to address the root cause of the disease.

Symptoms and Presentation of Erythema Nodosum

Erythema nodosum is characterized by several distinct symptoms and a unique presentation. Recognizing these symptoms is crucial for timely diagnosis and appropriate treatment. Individuals with erythema nodosum may experience:
