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 grouped in the emerging entities of the Vancouver modification of the 2004 WHO classification of renal neoplasia.[1]
General
- Extremely rare - only approximately 10 cases described as of 2012.[1]
- May be assocated with paraganglioma (as with several SDH mutations).
- Primarily described with a SDHB mutation.[2]
- SDHC has been described.[3]
Microscopic
Features:[2]
- Oncocytic cells with flocculent cytoplasmic inclusions.
- Intratumoural mast cells.
- Solid architecture.
DDx:
Images
- SDHB-RCC - poor quality histology image (nih.gov).[3]
- SDHC-RCC (nih.gov).[3]
- SDH-deficient RCC (nature.com).[2]
IHC
Features:
- SDHB -ve (11 of 11 cases[2]).
- CD117 -ve - important.
