Introduction: Most hamartomas are located peripherally in the lung parenchyma and are rarely identified as an endobronchial lesion. Clinically patients with an endobronchial hamartoma are often symptomatic and may present with various symptoms including: fever, wheezing, hemoptysis and obstructive pneumonia.
Case presentation: A 68-year-old man presented with complaints of fever and cough for 1 month. Chest X-ray revealed a right infrahilar density, which on chest CT was found to be a lesion obstructing the superior segmental bronchus of the right lower lobe and extending outside of the bronchus. A round rubbery mass obstructing the same segmental bronchus was noticed during bronchoscopy and endoscopic biopsy yielded a pathological diagnosis of hamartoma.
Discussion: Bronchoscopy is most helpful in diagnosis and management of endobronchial hamartomas but if the lung distal to the obstruction is irreversibly damaged or imaging studies suggest that tumor extends outside of the bronchus, pulmonary segmentectomy, lobar resection or even pneumonectomy may be indicated.
Conclusion: When a benign tumor of the lung, as endobronchial hamartoma, is located in a segmental bronchus and presents extrabronchial spread, we recommend to perform a parenchymal-sparing surgical resection. In this case surgical team, however, should keep in mind, due to difficult individual dissection of the segmental bronchovascular elements, the possibility of conversion from VATS (video-assisted thoracic surgery) to open thoracotomy.
