18
Q

CENTRALLY occurring lung cancer with Kulchitsky cells

A

Small cell

19
Q

Small cell metastasises….?

A

Early

20
Q

Lung cancer with highest rate of p53/c myc mutations

A

Squamous cell

21
Q

Occurs in women and non smokers

A

Adeno Ca

22
Q

Large cells
large nuclei
Poor prognosis

A

Large cell Ca

23
Q

Lung Ca showing keratinisation and intercellular prickles

A

Squamous cell (prickles = desmosomes)

24
Q

Which is more chemosensitive and why?

A

Small cell more chemosensitive as NSCLC has ERCC1 mutation that gives poorer response to cisplatin

25
Q

Definition of pulmonary hypertension?

A

Mean pulmonary arterial BP > 25 mmHg

26
Q

Expanded lung, firm, airless and plum coloured

A

Diffuse alveolar damage

27
Q

Heart failure cells

A

Iron-laden macrophages seen in pulmonary oedema

28
Q

Saddle embolus for PE?

A

Occludes pulmonary trunk

*risk death if more than 69% pulmonary bed occluded

29
Q

EGFR targeted in which lung Ca?

A

AdenoCa

30
Q

EML4-ALK mutation in?

A

AdenoCa

31
Q

Centrilobular emphysema?

A

Smoking

32
Q

Panacinar emphysema?

A

a1AT deficiency
