Dumbbell shaped exophytic and endobronchial lipomatous hamartoma.
ABSTRACT A 63-year-old man presented with a dumbbell-shaped mass obstructing his left upper lobe. He underwent a left upper lobectomy for suspected malignancy. An unexpected pathological diagnosis of endobronchial lipomatous hamartoma was made. Only 6 other cases have been reported in the English literature and only two cases were both endobronchial and exophytic.

ABSTRACT: Less than 1% of lung neoplasms are represented by benign tumors. Among these, hamartomas are the most common with an incidence between 0.025% and 0.32%. In relation to the localization, hamartomas are divided into intraparenchymal and endobronchial. Clinical manifestation of an endobronchial hamartoma (EH) results from tracheobronchial obstruction or bleeding. Usually, EH localizes in large diameter bronchus. Endoscopic removal is usually recommended. Bronchotomy or parenchimal resection through thoracotomy should be reserved only for cases where the hamatoma cannot be approached through endoscopy, or when irreversible lung functional impairment occurred after prolonged airflow obstruction. Generally, when endoscopic approach is used, this is through rigid bronchoscopy, laser photocoagulation or mechanical resection. Here we present a giant EH occasionally diagnosed and treated by fiberoptic bronchoscopy electrosurgical snaring.Journal of Cardiothoracic Surgery 08/2011; 6:97.
