摘要

Pancreatic metastases of renal cell carcinoma, like pancreatic neuroendocrine neoplasms, are hypervascular tumors, so their differentiation is often difficult. In addition, renal cell carcinomas are also often positive for somatostatin receptor scintigraphy, which has been recognized as a diagnostic imaging tool, especially for neuroendocrine neoplasms. We herein report a case of pancreatic metastasis of renal cell carcinoma positive for somatostatin receptor scintigraphy in which the diagnosis was made by EUS-FNA 12 years after the resection of renal cell carcinoma and the expression of somatostatin receptor subtypes in the resected specimens of pancreatic metastasis was examined.
