 note = {We investigated four cases whose sputum cytology were positive, while chest X-ray film, computed tomography, and bronchoscopic examination were negative. Bronchoscopic examination was performed as far as the segmental bronchi of the right upper lobe, right middle lobe, right lower lobe, left upper' lobe, and left lower lobe bronchi on different days. Brushing cytology and cytology of bronchial secretions were performed for each segmental bronchi with a freshly sterilized fiberscope and brush. In two cases, cancer cells were found and could be locaJ,ized. One was diagnosed as squamous cell carcinoma in the right B3 and the other as squamous cell carcinoma in situ in the periphery right B3ai. In two cases, the tumors could not be localized in spite of repeated bronchoscopic examination. To localize occult lung cancer, detailed bronchoscopic information must be combined with brushing cytology and bronchial secretion cytology after brushing from all the segmental bronchi using a freshly sterilized fiberscope and brush. In the present series, however, two ,of four cases could not be 10calized. Further examinations are needed. 喀疲細胞診陽性で,胸部X線およびCT無所見がつ気管支鏡無所見の4症例の局在診断の方法を検討した.右上,中,下葉,左上,下葉の各支に対して目を変えて気管支鏡検査を施行した.肺葉内の各区域支ごとにファイバー,ブラシを変更し,擦過細胞診及び気管支洗浄を施行した.2例で悪性所見が再確認され,局在診断ができた.1例は右B3の扁平上皮癌と診断された.他の1例は右B3。、末梢発生上皮内癌,扁平上皮癌と診断された.他の2例は,繰り返す気管支鏡検査でも病巣の同定に至らなかった.occuLt lung cancerの局在診断には可視範囲の緻密な観察のみならず各肺葉,各区域支ごとにファイバー,ブラシを交換し,擦過細胞診及び気管支洗浄を施行する必要があった.しかし,自検例ではこれらの方法でも4例中2例が局在診断に至らず今後の問題と考えられた., 金沢大学医薬保健研究域医学系},
