Fibrous histiocytomas are rarely found within the lung and have presented as a mass within a major airway only twice previously. This is the third reported case of such a tumor visualized roentgenographically in an airway on the frontal chest film of a patient presenting with recurrent pneumonia.
纤维组织细胞瘤在肺部很少见，此前仅两次表现为大气道内的肿块。这是第三例经影像学检查发现的此类肿瘤，该患者因反复肺炎行胸部正位片检查时，在气道内发现了肿瘤。
