A 73-year-old male was admitted to Hyogo College of Medicine Hospital for further evaluation of chest x-ray abnormalities. Chest roentgenogram taken at admission showed right lower lobe atelectasis and bronchoscopic examination revealed an endobronchial tumor obstructing the left lower lobe bronchus. The biopsy specimen showed cribriform adenoid cystic carcinoma. The serum CA19-9 level was markedly elevated at admission, leading to immunohistochemical analysis of the biopsy specimen. As a result, in the tumor, CA19-9 was positively stained. This is probably the first reported case of adenoid cystic carcinoma of the bronchus which produces CA19-9.
一名73岁男性因胸部X线异常进一步评估而入住兵库医科大学医院。入院时拍摄的胸部X线片显示右下叶肺不张，支气管镜检查发现左肺下叶支气管内有肿瘤阻塞。活检标本显示为筛状腺样囊性癌。入院时血清CA19-9水平显著升高，因此对活检标本进行了免疫组化分析。结果，肿瘤中CA19-9呈阳性染色。这可能是首例报道的产生CA19-9的支气管腺样囊性癌病例。
