LUNG - Fibrocaseous tuberculosis

The specimen consists of the outer part of a lung. The lung has been removed with the parietal pleura, which is grossly thickened, and obviously firmly adherent to the visceral pleura. At the lower pole there appears to be a portion of the diaphragm. The cut surface shows extensive tuberculosis, involving the greater part of the lung, and there is a discrete white area related to the upper cavity, which makes one wonder if a tumour is not developing there. In the lower part of the specimen, marked bronchiectasis can be seen.
