[Clofazimine--therapeutic alternative in necrobiosis lipoidica and granuloma anulare].

Twenty patients, ten suffering from disseminated granuloma anulare and ten from necrobiosis lipoidica, were treated with clofazimine 200 mg p.o. daily. Six patients in each group (60%) responded to this regimen, and three of the responders in each group achieved complete remission of the dermatosis. In eight patients (40%) no improvement at all was observed. All the patients treated had reddening of the skin, but this was reversible after the end of therapy, as were the other side-effects, i.e. diarrhoea and dryness of the skin, which were not experienced by all patients.
