Succinate dehydrogenase-deficient renal cell carcinoma
Succinate dehydrogenase-deficient renal cell carcinoma, also succinate dehydrogenase renal cell carcinoma (abbreviated SDH-RCC), is a very rare type of renal cell carcinoma that is grouped in the emerging entities of the Vancouver modification of the 2004 WHO classification of renal neoplasia.[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]

- Intratumoural mast cells.
- Solid architecture.
