Abstract
Pulmonary hamartomas are rare benign tumors, with a prevalence of 0.25% in the general population, accounting for approximately 8% of all benign lung neoplasms. Only 10% of pulmonary hamartomas are endobronchial in location, while the rest are peripheral. We report the case of a 50-year-old woman presenting with right basal thoracic pain lasting four months, associated with exertional dyspnea and a dry cough, all occurring in a context of general health deterioration. A chest CT scan revealed a calcified mediastinal-pulmonary lesion in the right lower lobe, causing lobar atelectasis. Flexible bronchoscopy revealed a tumor mass bridging the orifice of the right lower lobe and the middle lobe bronchus (Fowler’s segment), associated with infiltrative stenosis. The diagnosis of endobronchial hamartoma was confirmed after pneumonectomy. The postoperative course was favorable, with significant clinical improvement observed after one year.
