Tracheobronchial granulomatosis with polyangitis in a 57-year-old patient with a long history of multisystemic disease. (i) Axial MDCT scan shows a diffuse thickening of the bronchial wall, including the posterior wall, which helps to differentiate it from polychondritis. (ii) Coronal VRT reconstruction demonstrates stenosis on the subglottic area and left main bronchus. (iii) Photomicrograph (original magnification, ×20; haematoxylin-eosin stain) shows a necrotising granulomatous lesion with focal vascular destruction. The shape of the granuloma is elongated and the material in the necrotic centre has abundant nuclear debris
