title: Erythema induratum (Bazin's disease).
abstract: Four patients with erythema induratum (EI) have been diagnosed at the Dermatology Department within the past two years. All four patients had a history of recurrent painful nodules on their calves for at least three years before diagnosis. Three of the patients, all with positive Mantoux reaction to tuberculin skin tests, had neither a personal or family history of tuberculosis. The other patient who had a six year history of recurrent painful leg nodules developed a tuberculous breast abscess. There was a dramatic response to anti-tuberculous chemotherapy in all four patients but one subsequently had recurrent nodules which spontaneously subsided without further chemotherapy.
