A 58-year-old man admitted to hospital because of hemoptysis. Chest X-ray showed a large mass in the right middle lobe. A tumor marker CYFRA was slightly elevated. Despite a detailed examination after admission, no definite diagnosis was made. Lung cancer was suspected and a middle lobectomy was performed. Histopathological specimen of resected lung showed typical "sulfur granule" of actinomycosis. Pulmonary actinomycosis should be included in the differential diagnosis of a pulmonary mass lesion.
一名58岁男性因咯血入院。胸部X线显示右中叶有一个大肿块。肿瘤标志物CYFRA略有升高。入院后尽管进行了详细检查，但仍未明确诊断。怀疑为肺癌并进行了中叶切除术。切除肺的组织病理学标本显示典型的放线菌病“硫磺颗粒”。肺放线菌病应列入肺部肿块病变的鉴别诊断。
