Of the total, 30(60%) cases presented with type 1 reaction and 20(40%) with type 2. Further, 30(60%) cases were classified as borderline lepromatous. Among them, 17(57%) had type 2 reaction. Inflamed plaques were the main feature in 27(90%) cases of type 1. Crops of painful, erythematous nodules were seen in 19(95%) cases of type 2.
