Tumor-to-tumor metastases are very rare events. We report a case of a 64-year-old man who presented with a tumor of the pancreas. The patient underwent partial pancreatectomy. Frozen section diagnosis of the tumor was an endocrine neoplasm. Paraffin block slide examination revealed a tumor consisting of two components: pancreatic endocrine neoplasm at the periphery of the tumor and the central part composed of clear cells with delicate vessels. The results of immunohistochemical stains revealed renal cell carcinoma surrounded by pancreatic endocrine neoplasm, therefore representing an unusual case of renal cell carcinoma metastasizing to a pancreatic endocrine neoplasm.
肿瘤-to-肿瘤转移是非常罕见的事件。我们报告一例64岁男性，其患有胰腺肿瘤。该患者接受了胰腺部分切除术。肿瘤的冰冻切片诊断为内分泌肿瘤。石蜡块切片检查显示肿瘤由两个部分组成：肿瘤周边为胰腺内分泌肿瘤，中央部分由具有纤细血管的透明细胞组成。免疫组化染色结果显示肾细胞癌被胰腺内分泌肿瘤所包围，因此代表了一例肾细胞癌转移至胰腺内分泌肿瘤的罕见病例。
