Erythema nodosum in darker-skinned individuals may appear as deep red, purplish, or dark brown painful nodules, usually on the lower legs, which can be harder to detect due to the skin tone. This condition is often associated with infections, medications, or inflammatory diseases, and it may leave behind areas of darker pigmentation after healing. Treatment focuses on addressing the underlying cause, using anti-inflammatory medications like NSAIDs, and sometimes corticosteroids to reduce symptoms.
