Machine of concealed source sex turns a sex pneumonic is one kind a qualitative sex that names with clinical pathology is pneumonic, COP was 1985 Epler [the pathology performance that 1] offers is pulmonary alveolus inside, fine bronchus of sex of alveolar canal, breath and eventually the independent disease that end fine bronchus has granulation organization to form inside antrum is planted, say to send a gender especially again machine of fine bronchitic companion turns out-of-the-way sex the gender is pneumonic , will nearly 20 years report gradually grow in quantity, easy infection, n/med tuberculosis, tumour, as nodal as lung disease, other a disease of qualitative sex lung promiscuous, reached my courtyard to received vivid check of treated bronchus lens lung 2008 2007 now (8 case that TBLB) wins pathology to confirm are analysed as follows.

概要： 隐源性机化性肺炎是一类以临床病理命名的间质性肺炎，COP是1985年Epler等[1]提出的病理表现为肺泡内、肺泡管、呼吸性细支气管及终末细支气管腔内有肉芽组织形成的独立病种，又称特发性闭塞性细支气管炎伴机化性肺炎，近20年来报道逐渐增多，易和肺部感染、结核、肿瘤、结节病、其他间质性肺疾病等混淆，现将我院2007年至2008年收治的支气管镜肺活检获得病理证实的8例病例分析如下。
