A 68-year-old male with a tracheostoma due to hypopharyngeal cancer was admitted because his chest computed tomography (CT) showed a small nodule in the right middle lobe. Following a partial resection of the right middle lobe, histopathological diagnosis of the resected sample was that of organizing pneumonia. Eleven months later, chest CT showed a mass with pleural indentation and spiculation in the right middle lobe. 18-Fluorodeoxyglucose-positron emission tomography showed significant accumulation in the middle lobe tumor mass shadow. The abnormal chest shadow that had developed around surgical staples suggested inadequate resection and tumor recurrence. As the abnormal radiological shadow was enlarging, middle lobectomy was carried out. Histological examination revealed that the tumor was a lung abscess without malignant features. This is a unique case of lung abscess mimicking lung cancer which developed around staples used during partial resection of the lung.
一名因下咽癌行气管造口术的68岁男性患者因胸部计算机断层扫描（CT）显示右中叶有一个小结节而入院。右中叶部分切除术后，切除样本的组织病理学诊断为机化性肺炎。11个月后，胸部CT显示右中叶有一个伴有胸膜凹陷和毛刺征的肿块。18氟脱氧葡萄糖正电子发射断层扫描显示中叶肿瘤肿块阴影有明显放射性浓聚。手术吻合钉周围出现的异常胸部阴影提示切除不彻底和肿瘤复发。由于异常放射学阴影在增大，遂行右中叶切除术。组织学检查显示肿瘤为无恶性特征的肺脓肿。这是一例独特的肺脓肿病例，其在肺部分切除术中使用的吻合钉周围发生，酷似肺癌。
