获得性免疫缺陷综合征(AIDS)的肺部机会感染和 Kaposis 肉瘤(KS)发病率和死亡率很高。当出现急性发热、呼吸困难、胸片异常怀疑为 AIDS 时,纤维支气管镜(下简称纤支镜)检查对卡氏肺囊虫、鸟型分支杆菌、巨细胞病毒、军团菌属、真菌检出率很高,而对肺 KS 检出率低。本文作者对8例 AIDS 伴 KS患者经纤支镜支气管活检,结果有7例在气管内发现 Acquired immunodeficiency syndrome (AIDS) has a high incidence of lung opportunistic infections and Kaposis sarcoma (KS) morbidity and mortality. When acute fever, dyspnea, and chest X-ray abnormality are suspected as AIDS, fiberoptic bronchoscopy (hereinafter referred to as bronchoscopy) is used to detect Pneumocystis carinii, Mycobacterium avium, cytomegalovirus, Legionella, and fungi. The rate is high, and the detection rate of lung KS is low. The authors of this study performed bronchoscopic biopsy of bronchial bronchoscopy in 8 patients with AIDS-associated KS and found that 7 cases were found in the trachea.
