Allergic Bronchocentric Granulomatosis. low power. Sections show muscle, lung with acute inflammation and evidence of organisation with early fibrosis. The bronchial wall can be seen with chronic inflammation and many eosinophils.There is a thickened basement membrane. No definite granulomata are seen.

CXR prior to bronchoscopy had shown an opacity just superior to the right hilum, which was felt to represent possibly a fungal plug. Patient was therefore bronchoscoped.
