A distinctive, low‐grade oncocytic fumarate hydratase‐deficient renal cell carcinoma, morphologically reminiscent of succinate dehydrogenase‐deficient renal cell carcinoma

Abstract

In summary, we characterize a novel oncocytic type of FH-deficient RCC with a striking resemblance to SDH-deficient RCC, posing a diagnostic challenge and raising concerns about sampling and multifocality for syndrome-associated cases under surveillance protocols.
