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]
    • SDHA has been described.[3]
    • SDHC has been described.[4]
  • 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.

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]
