52-year-old woman who had had cough and bloody sputum for four years was admitted for detailed examination. Bronchoscopy revealed a yellow smooth polypoid tumor obstructing the right middle lobe bronchus. Chest CT scan showed a mass with a low CT number (from -70HU to -140HU) in the atelectatic region of the middle lobe. Right middle lobectomy was performed to obtain complete resection of the tumor. Pathological examination confirmed endobronchial lipoma with irreversible organizing pneumonia of the right middle lobe. The patient had a good postoperative couse and is alive 13 months after surgery without any respiratory symptoms. Endobronchial lipoma is one of the rarest bronchial neoplasms.
