title: Right Upper Lobe Shadow and Tracheobronchopathia Osteochondroplastica Confined to Right Main Bronchus: A Case Report and Literature Review.
abstract: Tracheobronchopathia osteochondroplastica (TO) is a well documented benign entity of endoscopic interest. We describe a case of 76-year-old patient who presented with fever, cough, purulent sputum during the past four days, and presence of an ovoid shadow in right upper zone of his chest X-ray. Medical history included diagnosis of colon diverticuli identified by colonoscopy 3 months ago. Chest CT revealed a compact elongated lesion containing air-bronchogram stripes. Bronchoscopy showed normal upper airways and trachea but presence of unequal sized mucosal nodules, protruding into the lumen, along the entire length of the right main bronchial mucosa. No other abnormal findings were detected. Moreover, brushing and washing smears from the apical segment of right upper lobe (RUL), where the compact lesion was located, were negative for malignancy. Biopsy from the mucosal nodules of right main bronchus showed presence of cartilaginous tissue in continuity through thin pedicles with submucosal cartilage. This finding posed the diagnosis of TO while RUL lesion was cleared by antibiotic treatment. Case is reported because, to our knowledge, it represents a unique anatomic location of TO which was confined exclusively in the right main bronchus mucosa without affecting trachea.
