Primary Lung Cancer that Developed Lung Abscess after Bronchoscopy and Was Cured by Surgery：Report of a Case

はじめに　気管支鏡検査後の肺膿瘍は日常的に遭遇する合併症であるが，発症すると治療に難渋する．われわれは気管支鏡検査を契機に原発性肺癌に肺膿瘍を併発したが，早期に手術することにより治癒できた1例を経験したので報告する．

The patient was a 72-year-old man. Chest computed tomography （CT） scan revealed a mass in the right lower lobe, so he underwent bronchoscopy. The pathological findings revealed squamous cell carcinoma. He was discharged the day after the examination, but was admitted to the hospital seven days later for fever. Chest CT scan showed a lung abscess at the site of the mass in the right lower lobe, so he was admitted to the hospital on an emergency basis. After admission, treatment with tazobactam and piperacin 13.5 g/day was started, but there was little improvement, so the decision was made to perform surgery, and a right lower lobectomy was performed via thoracotomy five days after the admission. The postoperative course was uneventful, and the patient was discharged on the 19th day after surgery. As the surgery was immediately performed after confirming that antimicrobial agents were ineffective, the patient was cured without any complications.
