title: Erythema induratum of bazin.
abstract: Erythema induratum of Bazin is a chronic, nodular eruption that usually occurs on the lower legs of young women. It has been regarded as a manifestation of tuberculin hypersensitivity, a type of tuberculid occurring on the legs, whereas nodular vasculitis represents the nontuberculous counterpart. The number of reports of erythema induratum of Bazin is decreasing in most developed countries in accordance with the decreased incidence of tuberculosis. The etiopathogenesis of erythema induratum of Bazin and its relation to tuberculosis are still controversial, because mycobacteria cannot be cultured from the skin lesions. Most authors currently consider erythema induratum of Bazin (nodular vasculitis) a multifactorial disorder with many different causes, tuberculosis being one of them.
