Abstract:
The case was 56 years old male. An abnormal shadow was pointed out by chest computed tomography (CT) at a medical examination. The CT scan revealed a 13 mm mass shadow that contacts with the B5a of the right middle lobe. Bronchoscopy revealed a yellow colored lesion that occluded B5ai. A non-cartilage type endobronchial hamartoma was suspected and the biopsy was performed, but a definitive diagnosis was not achieved. The lesion was surgically resected by the right middle lobectomy, and the histopathological diagnosis was an endobronchial hamartoma consisting mainly of mature adipose tissue.
