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.
一名66岁女性双下肢出现红斑结节，自述多年前有淋巴结结核病史，曾接受手术及抗结核治疗。取自一个结节的活检显示为结节性血管炎。石蜡包埋组织的结核分枝杆菌特异性DNA聚合酶链反应（PCR）结果呈阳性。基于我们对该患者的经验，对结节性血管炎病变中结核分枝杆菌特异性DNA的PCR阳性结果进行了批判性讨论。阐述了诸如硬结性红斑（巴赞红斑）等“结核疹”的历史背景。
