title: [Endobronchial Hamartoma Requiring Lobectomy;Report of a Case].
abstract: We present a rare case of endobronchial hamartoma that required right middle and lower lobectomy. A 59-year-old man presented with cough and sputum lasting for 9 months. Chest X-ray revealed obstructive pneumonia of the right inferior lobe. Chest computed tomography demonstrated an intrabronchial mass lesion, size 12×12 mm, occluding the entrance of the right lower lobe bronchus associated with obstructive pneumonia of the right inferior lobe. Because transbronchial biopsy could not confirm the diagnosis, we performed a right middle and lower lobectomy to diagnose and treat obstructive pneumonia. Histopathological diagnosis of the tumor was hamartoma. Hamartoma, the most common benign lung tumor, is classified into the following 2 types:pulmonary parenchyma and endobronchial, the latter is relatively rare. Although hamartomas have benign characteristics, cases of endobronchial hamartomas associated with obstructive pneumonia may require lobectomy.
