Gastric metastases from primary renal cell carcinoma (RCC) are rare and poorly documented in the existing literature. This case report presents the clinical course of a 65-year-old male with multi-metastatic clear cell RCC (ccRCC) who was incidentally found to have stomach metastases during follow-up magnetic resonance imaging (MRI). Gastric metastases from ccRCC are typically associated with other metastatic sites. They often emerge at an advanced stage of the disease, indicating a poor prognosis. It is therefore important to consider gastric metastases as a potential site of involvement in RCC patients. MRI revealed three gastric mucosal lesions exhibiting hypervascularity, a characteristic feature of ccRCC. Histological analysis confirmed the presence of malignant cells compatible with RCC.
原发性肾细胞癌（RCC）的胃转移罕见，现有文献中记载较少。本病例报告介绍了一名65岁男性多转移性透明细胞肾细胞癌（ccRCC）患者的临床病程，该患者在随访磁共振成像（MRI）时偶然发现有胃转移。ccRCC的胃转移通常与其他转移部位相关。它们常出现在疾病晚期，提示预后不良。因此，将胃转移视为RCC患者可能受累部位很重要。MRI显示三个胃黏膜病变表现为血管增多，这是ccRCC的一个特征性表现。组织学分析证实存在与RCC相符的恶性细胞。
