A 69-year-old woman was referred to our hospital due to an abnormal shadow on a chest roentgenogram. Computed tomographic scanning revealed a complete atelectasis of the left lower lobe. Though the definitive diagnosis was not obtained preoperatively, we performed a left lower lobe excision because atelectasis existed for more than one year. Immunohistochemical staining showed that tumor cells were positive for vimentin, CD34, bcl-2, CD99, and negative for S-100, α-smooth muscle actin. The tumor was diagnosed as a solitary fibrous tumor of the bronchus, which has been rarely reported to date.
一名69岁女性因胸部X线片出现异常阴影而被转诊至我院。计算机断层扫描显示左肺下叶完全肺不张。尽管术前未明确诊断，但由于肺不张已存在一年多，我们还是进行了左肺下叶切除术。免疫组织化学染色显示肿瘤细胞波形蛋白、CD34、bcl-2、CD99呈阳性，S-100、α平滑肌肌动蛋白呈阴性。该肿瘤被诊断为支气管孤立性纤维瘤，迄今为止鲜有报道。
