Abstract:
A 69-year-old man was hospitalized for fever and cough. He was diagnosed with and treated for an abscess in the left lower jaw and pneumonia by an otolaryngologist, but the pneumonia persisted with no improvement. Chest computed tomography revealed the presence of a heterogeneous torose lesion in the inlet of the left upper bronchus, and bronchoscopy revealed an endobronchial tumor with a smooth surface. An episode of sudden dyspnea occurred and was resolved after the patient changed his sitting position. We concluded that this symptom occurred because the tumor was incarcerated in the left lower lobe bronchus. The tumor was excised by bronchofi berscopic snare resection under tracheal intubation. It was found to be a pleomorphic carcinoma, and left upper lobectomy was performed. There has been no recurrence during the 3 years since the operation.
