LUNG - Bronchial adenoma

The specimen consists of a segment of lung, showing a bronchus and some of its subdivisions; the bronchus is largely occluded by a spherical tumour 2 cm. in diameter, showing some pale areas and some areas of haemorrhage. The bronchus leading away from the tumour shows a little dilatation. The lung tissue appears partly collapsed. This is a simple bronchial adenoma, with a minor degree of bronchiectasis.
