title: [Erythema induratum Bazin. "Tuberculid" or tuberculosis?].
abstract: A 66-year-old woman presented with erythematous nodules on both legs and told of a history of lymph node tuberculosis that had been treated with surgery and tuberculostatic therapy years before. A biopsy taken from a nodule showed nodular vasculitis. PCR for Mycobacterium tuberculosis-specific DNA on the paraffin-embedded tissue was positive. Based on the experience with our patient, positive PCR results for Mycobacterium tuberculosis-specific DNA in lesions of nodular vasculitis are discussed critically. The historical background of "tuberculids", such as erythema induratum Bazin, is elucidated.
