An experienced pathologist can make a diagnosis or at least think of a differential diagnosis by looking at the gross specimen.

You need experience to reach that stage.

Here are some exciting examples of macroscopic Lung and Pleural Specimens.


 

1)

 

Do you think this is a normal lung or is there some abnormality?

The lung shows several areas of

(A) Pleural Thickening and infolding. (B) There is incorporation of parietal pleural fat.


2)   

 

This is a typical appearance of which tumour? Can you think of a differential diagnosis?

Typical appearance of a mesothelioma which diffusely thickens the parietal and visceral pleura and extends along the fissure.

This appearance is not pathognomonic of mesothelioma and can be mimicked by other tumours, particularly adenocarcinoma (so-called pseudomesothelioma)


3)

 

Why is this block from the pleura important?

It is essential to take blocks from area where the pleura is puckered for assessment of visceral pleural invasion.


 

4)

Any idea what is happening in this lung specimen ?

A) This is a small fleshy endobronchial tumour.

(Microscopic appearance showed that it is a carcinoid tumour)

B) The tumour caused obstructive pneumonitis affecting the entire lobe distal to the tumour.

 


5)

Can you identify the lesion in this image?

A) Macroscopic specimen shows a yellowish mass-like consolidation throughout much of the lobe.

B) There is relative preservation of airways within the tumour when compared to the surrounding involved parenchyma.

Microscopic examination showed that the tumour is a low grade lymphoma of MALT origin.


6)

What is this image showing?

This is another image of the same tumour (5). Here the tumour shows extension at its periphery along an interlobular septum. Note that the pulmonary vein remains patent.


7)

What is a bee doing near a lung specimen?

This is part of a segment of lung showing "honeycomb appearance".
