The specimen shows a rather poorly defined tumour some 5 cm across in the lower part of the lobe.
There is no obvious direct connection with a major bronchus. The tumour is partly necrotic in the
central area; there is surrounding consolidation of the lung perhaps seen best on the reverse of the
specimen; the lung is adherent to the diaphragm. The lymph nodes in the hilar area do not
obviously contain tumour. the rest of the lung shows diffuse emphysema.
This specimen came from a middleaged man who had been found dead. He showed
advanced chronic obstructive respiratory disease and the immediate cause of death was an
associated acute bronchitis from which haemophilus influenzae was recovered. The tumour was a
squamous cell carcinoma which was moderately well differentiated; no metastases were found.
