Bronchiolitis Obliterans Organizing Pneumonia and Bronchogenic Carcinoma Coexisting in Different Parts of the Lungs

Bronchiolitis obliterans organizing pneumonia (BOOP) coexisting with nonsmall cell lung cancer in a separate part of the lungs is rare. We report the case of a man diagnosed with BOOP by video-assisted thoracoscopic lung biopsy; the patient also had adenocarcinoma in a different part of the lungs. The BOOP was treated with corticosteroids and the carcinoma was surgically resected. Outcome and clinical course were good after both procedures. The possibility of BOOP associated with bronchogenic carcinoma at a distant part of the lungs, although rare, must be taken into account in the differential diagnosis of radiographic alterations that may present in either of the 2 diseases.
