Reactions in leprosy are acute inflammatory episodes that can be classified as type I or type II. Recognition and timely management of these patients is critical to avoid permanent disability. We present two cases of erythema nodosum leprosum, presenting with recurrent atypical features, responding well to a low dose of methotrexate.
