Squamous cell carcinoma of the lung, also lung squamous cell carcinoma, is a common malignant lung tumour that is associated with smoking.
General
- Strong association with smoking.
- May be treated with surgery.
Gross
- Usually centrally located, i.e. large airways.
Microscopic
Features:
- Central nucleus.
- Dense appearing cytoplasm, usu. eosinophilic.
- +/-Small nucleolus.
DDx:
- Metastatic squamous cell carcinoma.
- Adenocarcinoma of the lung.
- Non-small cell lung carcinoma - diagnosis should be avoid if possible.
IHC
- p40 +ve.[1]
- p63 +ve -- less specific.
- TTF-1 -ve.
- Positive in adenocarcinoma.
- Calponin -ve.
- CK5/6 +ve.
