误诊为肺结核瘤的ANCA相关性血管炎临床分析OACSTPCD

Objective To explore the causes of misdiagnosis of anti-neutrophil cytoplasmic antibodies(ANCA)-associatedvasculitis and the preventive measures.Methods The clinical data of 1 patient with ANCA-associated vasculitis misdiagnosed were retrospectively analyzed.Results The patient was admitted to the hospital due to red rash of lower extrem-ity with ulcer.Operation for sinusitis had been performed in other hospitals,and pulmonary mass resection was performed in another hospital because pulmonary mass had been found during preoperative screening.Postoperative pathology revealed pul-monary tuberculoma,and the treatment was ineffective after anti-tuberculosis therapy.After admission,the patient was diag-nosed with ANCA-associated vasculitis based on the manifestations of multi-system involvement,laboratory examination and pathological examination of renal puncture.The symptoms were relieved by glucocorticoid and modulated immunotherapy.Conclusion The clinical manifestations of ANCA-associated vasculitis are diverse and atypical,which,therefore,is more likely to lead to misdiagnosis.In clinical practice,relevant medical examination should be performed as soon as possible in suspected cases.
