腫瘍内膿瘍から膿胸を合併した肺癌の1例

Lung Cancer Complicated with Empyema Due to Intratumoral Abscess；Report of a Case

はじめに　膿胸を合併した肺癌は比較的まれとされている．われわれは，腫瘍内膿瘍と腫瘍による閉塞肺炎の進展により膿胸を合併した肺癌の手術を経験したので報告する．

A 73-year-old man was admitted to our hospital because of fever. A chest computed tomography （CT） scan revealed a 10-cm-sized irregular mass with air-fluid level in the left lower lobe, and sputum cytology revealed squamous cell carcinoma, which was diagnosed as a giant squamous cell carcinoma with intratumoral abscess. Later, the empyema developed and drainage was performed for empyema and intratumoral abscess. Two weeks later, left lower lobectomy and lymph node dissection were performed by posterolateral thoracotomy. After surgery, there were no serious complications or relapse of empyema.
