目的加深对结节病的临床特点、鉴别及治疗的认识,从而进一步准确的鉴别及诊断。方法对二例结节病误诊为肺结核的病例的病情特点、化验检查及误诊原因进行分析。结果结节病是一种多系统器官受累的肉芽肿性疾病,常侵犯肺、双侧肺门淋巴结,也可以侵犯全身几乎每个器官,早期影像学易与结核病相混淆,而病理学表现亦与结核病有相似之处,故容易误诊误治。结论应从临床特点及病理学表现上认真鉴别,必要时反复取病理,寻找证据。 Objective To deepen the understanding of the clinical features, identification and treatment of sarcoidosis to further identify and diagnose. Methods Two cases of sarcoidosis misdiagnosed as pulmonary tuberculosis in the disease characteristics, laboratory tests and misdiagnosis were analyzed. Results Sarcoidosis is a granulomatous disease involving in multiple organs and organs. It often invades lung and bilateral hilar lymph nodes. It can also invade almost every organ of the whole body. Early imaging is easily confused with tuberculosis. Pathological findings There are similarities with tuberculosis, so it is easy to misdiagnosis and mistreatment. Conclusions should be carefully identified from the clinical features and pathological manifestations, if necessary, take the pathology, looking for evidence.
