Abstract：
This case report presents a unique instance of small bowel perforation caused by solitary metastasis from renal cell carcinoma (RCC), a rare and complex clinical scenario. The patient, a 59-year-old male with a history of RCC treated with nephrectomy four years prior, presented with acute abdomen symptoms. Emergency diagnostic procedures identified a significant lesion in the small intestine. Surgical intervention revealed a perforated jejunal segment due to metastatic RCC. Postoperatively, the patient developed complications, including pneumonia and multi-organ failure, leading to death 10 days after surgery. Histopathological analysis confirmed the metastatic nature of the lesion. This case underscores the unpredictable nature of RCC metastasis and highlights the need for vigilance in post-nephrectomy patients. The rarity of small bowel involvement by RCC metastasis, particularly presenting as perforation, makes this case a significant contribution to medical literature, emphasizing the challenges in the diagnosis and management of such atypical presentations.
摘要：
该病例报告提供了一个由肾细胞癌（RCC）的孤立性转移引起的小肠穿孔的独特实例，罕见且复杂的临床情况。病人,一名59岁的男性，有肾癌病史，四年前接受肾切除术治疗，出现急腹症状.紧急诊断程序确定了小肠中的明显病变。手术干预显示，由于转移性RCC，空肠段穿孔。术后,病人出现并发症,包括肺炎和多器官衰竭,导致手术后10天死亡。组织病理学分析证实了病变的转移性。此病例强调了RCC转移的不可预测性质，并强调了肾切除术后患者的警惕性。罕见的小肠累及RCC转移，特别是表现为穿孔，使这个案例对医学文献做出了重大贡献，强调这种非典型表现的诊断和管理方面的挑战。
