A Resected Case of Simultaneous Gastric and Multiple Pancreatic Metastases of Renal Cell Carcinoma 11 Years After Nephrectomy.

A 50-year-old man with a history of nephrectomy for renal cell carcinoma (RCC) 11 years prior was diagnosed with gastric and multiple pancreatic metastases of RCC. He underwent a pyloric gastrectomy and total pancreatic resection. RCC metastases to the pancreas are rare, and gastric metastases are even rarer. This case represents a rare instance of simultaneous RCC metastases to both the stomach and pancreas. Although there is no difference in prognosis between solitary and multiple pancreatic metastases, surgical resection is recommended even for multiple lesions. However, preoperative imaging often fails to identify all pancreatic metastatic lesions, making total pancreatectomy a consideration for ensuring complete resection, especially when preoperative detection is challenging.
