ALK translocation renal cell carcinoma is a proposed entity within the Vancouver modification of the 2004 WHO classification of renal neoplasia.[1]
General
- Extremely rare.
- May be related to renal medullary carcinoma which is reported to have an ALK rearrangement - t(2;10)(p23;q22).[2]
- May respond to ALK inhibitors, e.g. Alectinib.[3]
Microscopic
Features:
- Mix of morphologies - including rhabdoid change, sarcomatoid change, "unclassified renal cell carcinoma", papillary renal cell carcinoma.
DDx:
IHC
- ALK +ve.
- SMARCB1 -ve.
