title: Erythema induratum of Bazin associated with Addison's disease: first description.
abstract: BACKGROUND
  Erythema induratum of Bazin (EIB) is considered to be a tuberculid reaction and consists of recurrent painful nodules. The differential diagnosis includes diseases like nodular vasculitis, perniosis, polyarteritis nodosa and erythema nodosum.
  
  
  METHODS
  We report the case of a woman with EIB who developed Addison's disease during treatment with anti-tuberculosis drugs with good response to glucocorticoid replacement. The diagnosis was obtained through the clinical picture, positive tuberculin test and positive BCG (bacillus Calmette-Guérin) test on the histological sample. Anti-tuberculosis drugs and glucocorticoid replacement led to disappearance of the signs and symptoms.
  
  
  CONCLUSIONS
  This is the first description of an association between EIB and Addison's disease. It should be borne in mind that tuberculosis is an important etiological factor for Addison's disease.
