Erythema nodosum is the most frequent clinicopathologic variant of panniculitis. Triggers are represented by infections, sarcoidosis, rheumatologic diseases, inflammatory bowel disease, medications, autoimmune disorders, pregnancy and malignancy. Erythema nodosum typically manifests by the sudden onset of symmetrical, erythematous, warm nodules, usually located on the lower limbs. Often the lesions are bilaterally distributed. Treatment of erythema nodosum should be directed to the underlying associated condition, if identified. Usually, nodules of erythema nodosum regress spontaneously within a few weeks, and bed rest is often sufficient treatment. Nonsteroidal antiinflammatory drugs and potassium iodide may be helpful drugs to enhance analgesia and resolution. Systemic corticosteroids are rarely indicated in erythema nodosum and before these drugs are administered, an underlying infection should be ruled out.
