We experienced a case of fumarate hydratase (FH) -deficient renal cell carcinoma (RCC) suspected of hereditary leiomyomatosis renal cell carcinoma (HLRCC) and herein report our findings. A 42-year-old man with an unremarkable medical history was referred to our hospital with an initial impression of renal cancer, cT3aN2M0. He underwent a right radical nephrectomy with lymph node dissection and showed a pathological diagnosis of FH-deficient RCC, pT3aN2. Clinicopathologic features indicated the possibility of HLRCC; however,-associated RCC. genetic testing showed negative for pathogenic FH mutation.
