Synchronous Renal Cell Carcinoma and Hepatocellular Carcinoma

摘要

The coexistence of multiple synchronous primary malignancies is uncommon. The coexistence of hepatocellular carcinoma (HCC) and renal cell carcinoma (RCC) is even rarer. We present a case of a 44-year-old male patient with a history of chronic hepatitis B and a right renal mass treated by radical nephrectomy. At the 2-month follow-up, a new lesion was detected in the left lobe of the liver. Postsurgery histologic evaluation with immunohistochemical study of both lesions confirmed the renal and hepatic lesions to be RCC and HCC, respectively.
