Lung carcinoma with ALK rearrangement is subset of lung adenocarcinoma.
General
Microscopic
Features:[1]
- Adenocarcinoma - at least focally.
- Solid signet-ring cell pattern - common.
- Mucinous cribriform pattern - common.
DDx:
Images
- Lung carcinoma with ALK rearrangement (nih.gov).[3]
- Lung carcinoma with ALK rearrangment (nih.gov)[4] - high resolution (plosone.org).
IHC
Features:[1]
- p63 +ve.
- TTF-1 +ve.
- ALK +ve.[citation needed]
Molecular
- EML4-ALK fusion -- inv(2)(p21p23).[5]
Notes:
- May be demonstrated with FISH or PCR looking for the a fusion transcript.[6]
- ALK rearrangement does not occur with EGRF mutation or KRAS mutation.[6]
