Endobronchial Squamous Cell Carcinoma Presenting as Long Continuous Bronchial Thickening on 18Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography

A 67-year-old man is presented with complaints of chest pain and productive cough for 1½ years. Chest X-ray was suggestive of right upper lobe Koch's lesion. Sputum was positive for mycobacterium tuberculosis. His symptoms got relieved partially by antitubercular treatment but the patient had an aggravation of symptoms for which he was evaluated. Computed tomography (CT) thorax revealed an endobronchial lesion in the right upper lobe bronchus. Bronchoscopy showed a mass in the right main bronchus and biopsy was suggestive of moderately differentiated squamous cell carcinoma (SCC). 18Fluoro-deoxy-glucose positron emission tomography/CT was performed for staging. There would have been chances of coexisting tuberculosis with SCC.
