Synchronous Renal and Hepatocellular Carcinomas

Summary Multiple synchronous primary tumours can cause diagnostic difficulties regarding primary origin versus metastatic spread. Greater awareness of concurrent carcinogenesis is necessary as more frequent occurrence of multiple primary cancers can be expected in future due to the growing tumour burden in the aging world population along with improved treatment efficacy. Here we report a 58-year-old male patient, who was diagnosed with two rare synchronous tumours: hepatocellular carcinoma and renal clear cell carcinoma. Both tumours were radically removed by simultaneous liver and kidney resection.
