Succinate dehydrogenase-deficient renal cell carcinoma 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]

General

  • Extremely rare - only recently described.
  • May be assocated with paraganglioma (as with SDH mutations).

Microscopic

Features:[2]

  • Oncocytic cells with flocculent cytoplasmic inclusions.
  • Intratumoural mast cells.
  • Solid architecture.

DDx:

IHC

Features:

  • SDHB -ve (11 of 11 cases[2]).
  • CD117 -ve.
