Abstract
We report two squamous cell lung carcinoma cases which developed an abscess after transbronchial lung biopsy (TBLB). Case 1 : A 73-year-old man developed a fever and cough two days after TBLB. Antibiotic treatment was not effective ; a left lower lobectomy +ND1 was performed. Ipsilateral pneumonia occurred after the operation, but the patient improved. Case 2 : A 61-year-old man developed a fever two days after TBLB. Antibiotic treatment was not effective ; a right lower lobectomy +ND2a was performed. Bilateral pneumonia occurred after the operation ; the patient was put on a respirator and required another operation because of prolonged air leakage. TBLB in lung carcinoma patients carries the risk of abscess formation. It is important not to delay surgery so as to improve patient outcomes.
