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

: 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.
