Increased cancer risk in patients with inflammatory and infectious diseases has been reported in many studies and lung cancer-associated empyema in <0.3% patients.

Purulent pleural fluid obtained by drainage or thoracentesis must always been examined because the association of malignant tumors and empyema should be taken into consideration.
Keywords: decortication; preoperative empyema; primary lung cancer; video‐assisted thoracoscopy.
