Pathological and radiological findings in a severe asthmatic patient. a A small bronchiole (arrow) presents goblet cell metaplasia and the lumen completely occupied by mucus, epithelial cells and eosinophils. In the peribronchial region lymphoid nodules are evident (arrowhead). b In the peribronchiolar alveolated tissue lymphoid infiltrates are evident (arrows) (H&E, low power). c High-Resolution CT scan at the lung base showing thickening of the wall and dilatation of the lumens of the bronchi and some centrilobular micronodules
