Description
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.
