Succinate dehydrogenase-deficient renal cell carcinoma, also succinate dehydrogenase renal cell carcinoma (abbreviated SDH-RCC), is a very rare type of renal cell carcinoma.
It is in the 2016 World Health Organization classification of renal neoplasia.
General
- Extremely rare - estimated to represent up to 0.2% of renal cell carcinomas.[1]
 - May be assocated with paraganglioma and familial, as with several SDH mutations.[2]
 - Primarily described with a SDHB mutation.[3]
 - Usually good prognosis.
 
Gross
- Mass lesion - commonly cystic.
 
Microscopic
Features:[3]
- Eosinophilic cells with clear (flocculent) cytoplasmic inclusions. ‡
 - Round nuclei with mildly granular chromatin pattern.
 - Intratumoural mast cells - usu. not prominent.
 - Solid architecture - typical.
 
Notes:
- ‡ Occasional cells may look like signet ring cells.
 - Typically low ISUP nucleolar grade.
- May be sarcomatoid.
 
 
DDx:
- Renal oncocytoma - granular cytoplasm.
 - Chromophobe renal cell carcinoma.
 - Clear cell renal cell carcinoma.
 - Other renal tumours with eosinophilic cytoplasm.

IHC
Features:
- SDHB -ve (11 of 11 cases[3]).
- Normal tubules +ve.
 - May be (pseudo)negative in clear cells (as few mitochondria).
 
 - CD117 -ve - important.
 - CA9 -ve.
 
Others:
- PAX8 +ve.
 - EMA +ve (10/10[3]).
 - CK7 -ve (1 +ve/35[1]).
 - AE1/AE3 -ve/+ve (4 +ve/10[3]).
 - CK20 -ve.
 - CD10 usually focal (most common) or -ve.[1]
