胸膜淀粉样变

Pleural amyloidosis

目的探讨胸膜淀粉样变在胸腔积液鉴别诊断中的意义。方法回顾性分析系统性淀粉样变病例中胸腔积液的发生率及其临床特点。结果１５例系统性淀粉样变中，７例（４７％）合并胸腔积液，其中４例由经皮针胸膜活检刚果红染色阳性而确诊为胸膜淀粉样变。结论系统性淀粉样变合并胸腔积液并非罕见。多器官损害合并胸腔积液时应疑及该病。经皮针胸膜活检具确诊价值。

Objective To evaluate the clinical significance of systemic amyloidosis in the differential diagnosis of pleural effusion . Methods Retrospective analysis of the incidence and the characteristics of pleural effusion in systemic amyloidosis. Results Seven (47%) of 15 cases of systemic amyloidosis were complicated with pleural effusion , of them 4 cases were confirmed by positive Congo red stain of percutaneous pleural biopsies specimens. Conclusions Systemic amyloidosis involving pleura was not rare. Pleural amyloidosis should be suspected in pleural effusion complicated by multiorgan disease. Percutaneous pleural biopsy with Congo red stain can confirm the diagnosis.
