Synchronous occurrence of hepatocellular carcinoma and renal cell carcinoma: A case report

The coexistence of two primary tumors is very rare. Additionally, hepatocellular carcinoma (HCC) and renal cell carcinoma (RCC) are even less frequent.An 81-year-old male patient had HCC and RCC synchronously. Surgery was performed primarily, as both tumors were suitable for resection. Adverse effects were observed during the patient's follow-up with adjuvant chemotherapy, and the treatment regimen was changed.This report presents the seventh case describing the treatment of synchronous double cancers of HCC and RCC. Although this rare condition shortens the patient’s life expectancy, our patient is alive even though he has a liver recurrence in the third month and is followed up to the 20th month.
