Bronchoscopic management of a primary endobronchial salivary epithelial-myoepithelial carcinoma: A case report

Here, we discussed a 55 y/o African man who recently immigrated from Nigeria to the United States and who presented to Parkland Memorial Hospital with a productive, intermittent cough of one year duration. The cough was associated with shortness of breath and chest pain. Cough was not associated with voice hoarseness, hemoptysis, melanoptysis, and wheezing. He had a computed tomography (CT) scan of the chest that showed a 1.9 cm mass in the right main stem bronchus with ipsilateral right lower lobe consolidation and bronchiectasis. The patient was seen by pulmonology who recommended bronchoscopy for diagnosis and possible intervention. Bronchoscopy showed a 90% obstructing mass in the proximal right mainstem bronchus and bronchus intermedius. The mass was large and endobronchial, circumferential, exophytic, and polypoid. The decision was made to undergo bronchoscopic tumor ablation using electrocautery snare, argon plasma coagulation (APC), suction, and forceps. The tumor was successful ablated. Microscopic examination revealed eosinophilic ducts tightly coupled with a surrounding layer of clear cell myoepithelial cells and the diagnosis of epithelial-myoepithelial carcinoma (EMC) of the lung was made. The patient was discharged from the hospital with scheduled outpatient visits for monitoring of the carcinoma by pulmonology and thoracic surgery. Unfortunately, he was lost to follow up.
